Assignment代写：Simulate Caches

下面为大家整理一篇优秀的assignment代写范文- Simulate Caches，供大家参考学习，这篇论文讨论了如何利用C语言模拟cache。

The goal of this assignment is to provide you a better understanding of caches. You are required to write a cache simulator using the C programming language. The programs have to run on iLab machines and should be tested with the autograder.

We are providing real program memory traces as input to your cache simulator. The format and structure of the memory traces are described below.

Memory Access Traces

The input to the cache simulator is a memory access trace, which we have generated by executing real programs. The trace contains memory addresses accessed during program execution. Your cache simulator will have to use these addresses to determine if the access is a hit, miss, and the actions to perform.

The memory trace file consists of multiple lines. Each line of the trace file corresponds to a memory accesses performed by the program. Each line consists of multiple columns, which are space separated. The first column reports the PC (program counter) when this particular memory access occurred, followed by a colon(:). Second column lists whether the memory access is a read (R) or a write (W) operation. And the last column reports the actual 48-bit memory address that has been accessed by the program. In this assignment, you only need to consider the second and the third columns (i.e. you don’t really need to know the PCs). The last line of the trace file will be the string #eof

Here is a sample trace file:

0x804ae19: R 0x9cb3d40

0x804ae19: W 0x9cb3d40

0x804ae1c: R 0x9cb3d44

0x804ae1c: W 0x9cb3d44

0x804ae10: R 0xbf8ef498

#eof

Cache Simulator (100 points)

You will implement a cache simulator to evaluate different configurations of caches. It should be able to run with different traces files. The followings are the requirements for your cache simulator:

1. Simulate only one level cache: L1

2. The cache size, associativity, and block size are input parameters. Cache size and block size are specified in bytes.

3. Replacement algorithm: First In First Out (FIFO). When a block needs to be replaced, the cache evicts the block that was accessed first. It does not take into account whether the block is frequently or recently accessed..

4. It’s a write through cache.

Running your Cache Simulator

You have to name your cache simulator first. Your program should support the following usage interface:

./first where:

A) < cachesize > is the total size of the cache in bytes. This number should be a power of 2.

B) < associativity > is one of:

– direct – simulate a direct mapped cache.

– assoc – simulate a fully associative cache.

– assoc:n – simulate an n − way associative cache. n will be a power of 2.

C) Here is valid cache policy is fifo.

D) < blocksize > is a power of 2 integer that specifies the size of the cache block in bytes.

E) < tracefile > is the name of the trace file.

Cache Prefetcher:

Prefetching is a common technique to increase the spatial locality of the caches beyond the cache line. The idea of prefetching is to bring the data into the cache before it is needed (accessed). In a normal cache, you bring a block of data into the cache whenever you experience a cache-miss. Now, we want you to explore a different type of cache that prefetches not only brings the block corresponding to the access but also prefetches one adjacent block, which will result in one extra memory read. An adjacent block to a memory address A is defined as follows: it is the block corresponding to the memory address A+ block_size.

For example, if a memory address 0x40 misses in the cache and the block size is 4 bytes, then the prefetcher would bring the block corresponding to 0x40 + 4 into the cache.

The prefetcher is activated only on misses and it is not active on a cache hit. If the prefetched block is already in the cache, it does not read the block from memory. With respect to cache replacement policies, if the prefetched block hits in the cache, the line replacement policy status should not be updated. Otherwise, it

is treated similar to a block that missed the cache.

Sample Run

Your program should print out the number of memory reads (per cache block), memory writes (per cache block), cache hits, and cache misses for normal cache and the cache with prefetcher. You should follow the exact same format shown below (pay attention to case sensitivity of the letters), otherwise, the autograder can not grade your program properly.

$./first 32 assoc:2 fifo 4 trace2.txt

no-prefetch

Memory reads: 3499

Memory writes: 2861

Cache hits: 6501

Cache misses: 3499

with-prefetch

Memory reads: 3521

Memory writes: 2861

Cache hits: 8124

Cache misses: 1876

In this example above, we are simulating 2-way set associate cache of size 32 bytes. Each cache block is 4 bytes. The trace file name is “trace2.txt”.

As you can see, the simulator should simulate both catch types with the prefetcher and without the prefetcher in a single run and display the results for both.

Simulation Details

1. (a) When your program starts, there is nothing in the cache. So, all cache lines are empty (invalid).

(b) you can assume that the memory size is 248 . Therefore, memory addresses are 48 bit (zero extend the addresses in the trace file if they’re less than 48-bit in length).

(c) the number of bits in the tag, cache address, and byte address are determined by the cache size and the block size;

(d) Your simulator should simulate the operation of a cache according to the given parameters for the given trace

2. For a write-through cache, there is the question of what should happen in case of a write miss. In this assignment, the assumption is that the block is first read from memory (one read memory), and then followed by a memory write.

3- You do not need to simulate the memory in this assignment. Because, the traces doesn’t contain any information on “data values” transferred between the memory and the caches.

4. You have to compile your program with the following flags: -Wall -Werror -fsanitize=address

Extra Credit (50 points):

As an extra credit, you should implement LRU (Least Recently Used) cache policy. Your program should output exactly the same format output as it shown before. Please note that, you should clearly mention in the report that you’ve done extra credit otherwise you may not get the points.

Here is an example of running your program with LRU policy.

$./first 32 assoc:2 lru 4 trace2.txt

no-prefetch

Memory reads: 3292

Memory writes: 2861

Cache hits: 6708

Cache misses: 3292

with-prefetch

Memory reads: 3315

Memory writes: 2861

Cache hits: 8331

Cache misses: 1669

Submission

You have to e-submit the assignment using Sakai . Put all files (source code + Makefile + report.pdf) into a directory named first, which itself is a sub-directory under pa4 . Then, create a tar file (follow the instructions in the previous assignments to create the tar file). Your submission should be only a tar file named pa4.tar. You have to e-submit the assignment using Sakai.

Your submission should be a tar file named pa4.tar. To create this file, put everything that you are submitting into a directory named pa4. Then, cd into the directory containing pa4 (that is, pa4’s parent directory) and run the following command:

$tar cvf pa4.tar pa4

To check that you have correctly created the tar file, you should copy it (pa4.tar) into an empty directory and run the following command:

$tar xvf pa4.tar

This should create a directory named pa4 in the (previously) empty directory. Your pa4 folder should contain the following:

• first: folder

• source code: all source code files necessary for building your programs.

Your code should contain at least two files: first.c and first.h. It should

contain code for regular credit and extra credit (if you attempt it). • Makefile: There should be at least two rules in your Makefile:

• first: build the executables (first).

• clean: prepare for rebuilding from scratch.

• report.pdf : In your report you should briefly describe the main data

structures being used in your program. More importantly, you should report your observation on how the prefetcher changed the cache hits and number of memory reads. Explain why?

Autograder First mode

Testing when you are writing code with a pa4 folder.

1. Lets say you have a pa4 folder with the directory structure as described in the assignment.

2. Copy the folder to the directory of the autograder

3. Run the autograder with the following command

$python auto_grader.py

It will run the test cases and print your scores.

Second mode

This mode is to test your final submission (i.e, pa4.tar)

1. Copy pa4.tar to the autograder directory

2. Run the autograder with pa4.tar as the argument as below:

$python auto_grader.py pa4.tar

Grading guidelines

1. We should be able build your program by just running make.

2. Your program should follow the format specified above for the usage interface. 3. Your program should strictly follow the input and output specifications mentioned above. (Note: This is perhaps the most important guideline: failing to follow it might result in you losing all or most of your points for this assignment. Make sure your program’s output format is exactly as specified. Any deviation

will cause the automated grader to mark your output as “incorrect”. REQUESTS FOR RE-EVALUATIONS OF PROGRAMS REJECTED DUE TO IMPROPER FORMAT WILL NOT BE ENTERTAINED.)

essay hook写作技巧分享

对于熟悉essay写作的留学生来说，开头可能会写得非常随意，因为他们都不知道还有essay hook这一说法。essay hook就是指essay开头的前几句话，其作用是为了引起读者的注意力，吸引他们。下面就给大家分享一下essay hook的写作技巧。

1.引用典文学

在写一篇关于某个作者、故事、文学现象、书籍等的文章时，这时候在开头使用essay hook可以说是很大的加分项。使用引语会使你的文章读起来很新鲜，并确立你作为作者的权威。

例如：“So we beat on, boats against the current, borne back ceaselessly into the past. These words of Nick Carr away perfectly describe…”

“Not all those who wander are lost.” And yes, indeed, every person is so…”

2.引用著名人物

恰当的引用著名人物，包括来自权威和有影响力的人的引用可以支持你的论点，列举的这位就是你文章的一个有趣的钩，钓着你的读者们的心。关键是要确保你清楚地表明这句话与你的文章有什么关系。

例如“John Wooden once said, ‘Never mistake activity for achievement.’”

“Learn to laugh” were the first words from my kindergarten teacher after Ralph Thorsen spilled paint on my daffodil picture.

3.收集轶事

当然了，不用担心因为essay hook的引用影响你后面的写作，即使是有趣的轶事开头，也并不意味着你的整篇文章必须是有趣的。一点幽默可以帮助你抓住读者的注意力，激发他们对这个话题的兴趣。

例：“As my cousin and I pedaled our new bikes to the beach, 6 years old, suntanned and young, we met an old, shaggy-haired man weaving unsteadily on a battered old bike.”

“When I was a young boy, my father worked at a coal mine. For 27 years, he made it his occupation to scrape and claw and grunt his way into the bowels of the earth, searching for fuel. On April 19, 2004, the bowels of the earth clawed back.”

Keep in mind that most essay assignments will ask you to avoid using the first person. Be sure to check any requirements before using “I” in your writing.

4.提出问题

几乎没有什么比一个精心构建的问题更能吸引人的兴趣了。读者们会想要继续阅读你的文章，以便找到答案。一定要避免简单的“是”或“否”的问题，并试着提出一些问题，让读者思考对方的另一面，或者进行一些批判性思维。

“What would you do if you could play God for a day? That’s exactly what the leaders of the tiny island nation of Guam tried to answer.”

“Have you ever wondered, whether Anna Karenina still loved Alexei if she hadn’t decided to commit a suicide?”

5.场景设置

人们对视觉线索的反应很好。花时间设定一个详细的场景可以帮助你的读者在脑海中清晰地描绘出一个清晰的画面，并创造一个有效essay hook。你可以描述一个事件或详细描述一个人或一个人物的特殊特征，帮助读者沉浸在你的写作中。

“The day of his birth began with Hurricane Charlie pounding at our door in Charleston, South Carolina.”

“Deciding to attend Hampton Roads Academy, a private school, was one of my most difficult decisions.”

以上就是关于essay hook的写作技巧分享，最重要的还是要同学们自己去琢磨essay hook的巧妙之处，学会运用。

Paper代写：Enterprise project management

下面为大家整理一篇优秀的paper代写范文- Enterprise project management，供大家参考学习，这篇论文讨论了企业项目管理。企业项目管理是指企业的高层管理人员对企业正在进行的项目任务进行项目管理，以企业长期发展为战略目标，完善企业项目管理体系，以优秀的项目管理团队为基础环境，提高企业项目管理能力。因此，企业应重视企业项目管理制度的建设，提高企业项目管理水平。

Enterprise project management refers to the enterprise's top management to the enterprise project management for the ongoing project tasks, for enterprise long-term development strategic target, perfect the enterprise project management system, on the basis of excellent project management team environment, and improve enterprise project management skills. Therefore, enterprises should attach importance to the construction of enterprise project management system and improve the level of enterprise project management.

Correct selection of enterprise project management makes the enterprises rapid development, the rapid development of the enterprise exposed the deficiencies in the project management enterprises, mainly the conflict between project management and function management, enterprise project management into, project selection is not reasonable in three aspects, from the three aspects below a brief overview.

The functions of the traditional enterprise management organization structure and project management pattern difference is bigger, at present, the project management in the enterprise is more and more attention, the project management and function management conflict continued to grow, the conflict between them there is no better solution. Therefore, enterprises should attach importance to scientific and rational adjustment of the conflict between the two, so as to make the enterprise healthy development.

Multiple project management conflicts are inevitable in various enterprises. If one enterprise only undertakes one project for a period of time, then the enterprise will face serious survival problems. Over a period of time to a centralized advantage for the project activity, for the enterprise is easy, yet at the same time for multiple projects, enterprises face the challenge of increasing difficulty, in the allocation of resources and project management way, need reasonable arrangement of enterprise, reduce the conflicts between projects and project management. In the process of multi-project management, we need to make rational use of the existing human resources and financial resources of the enterprise, so as to ensure the healthy and rapid development of the enterprise.

Enterprise project management is guided by the enterprise development strategy and finally realizes the strategic goal of long-term healthy development of the enterprise. Therefore, aligning the project goals with the strategic objectives of the enterprise is a problem that the enterprise managers need to solve as soon as possible. Scientific and rational choice for enterprise development project, managers need to correctly recognize the relationship between project management and enterprise strategy, suitable for enterprise development project is consistent with the enterprise development strategy, to promote the healthy and rapid development of enterprises, make the enterprise benefit maximization of the project.

Aiming at the deficiency of enterprise project management, puts forward the enhancement enterprise cognitive ability of project management, using the matrix structure and the choice of the reasonable project management mode of project management measures, improve the ability of enterprise project management, make the enterprise benefit maximization, promote enterprise long-term development.

In most enterprises in our country, the management of enterprise management, product management and the difference between enterprise project management is not clear, the cognitive mistake led to the direction of the management to other management method directly applied in project management, enterprise development. Some enterprises have realized the mistake, will project management in project process is separated from enterprise management area, according to the characteristics of the implementation of specific projects, management style, in the concrete practice in project management but also felt not clear direction. The characteristics of the project of an enterprise usually has a one-time, this feature determines no fixed mode of project management in project management can be applied, the enterprise project management should be based on specific project management plan, implement effective way of project management of the project, to ensure smoothly mean term purpose within the prescribed time.

Project cycle is long, generally in the stages of enterprise's manpower, financial resources and other resources have different requirements, therefore, project management and implementation of personnel work with the characteristics of a temporary members of temporary work to make their future uncertain, lead to members of the working mood is not high, thus affecting the work efficiency. Enterprises to adopt matrix of project management structure is effective to solve this problem, the project members in the project work is temporary, but the functions of the job is for a long time, solve the member worries about the future, to the enterprise project management is completed. The function of matrix project management structure depends on the degree of contact between project members and functional departments. The link between the two is too poor to resolve the concerns of project members; The connection is too strong, which may lead to the involvement of functional departments in the project, leading to excessive management, and secondly, the work of the project members in the functional departments. Properly handle project members and functional departments? F tonality is the focus of enterprise's current work.

Project management mode can be divided into cycle project management mode and functional project management mode. Therefore, project management is carried out on two dimensions. Cycle project management way consistent with the law of development of the project itself, therefore, the smooth completion of the project is natural, but the members of the management way there is a big problem is unstable, the cost is expected is not stable. On the contrary, the functional project management mode can utilize the enterprise functional department framework and functional staff, thus avoiding the problem of cost and personnel instability. However, the management of functional project is adapted to the repetitive management work, which is inconsistent with the one-off characteristics and existing laws of the project, thus affecting the project work efficiency. Both project management methods have their advantages and disadvantages, and the enterprise should decide the project management mode according to the specific project situation.

Enterprise project management is a necessary link in enterprise management, the reasonable project management mode can effectively improve the management level of the whole project, make the project smooth implementation and completion, make the enterprise benefit maximization, achieve the long-term development of the enterprise strategy. The enterprise implementation project management needs to improve the management personnel's awareness of the project management, build a good project management team, improve the economic benefit of the enterprise, and increase the competitiveness of the enterprise market.

Paper代写：The economic effect of accounting

下面为大家整理一篇优秀的paper代写范文- The economic effect of accounting，供大家参考学习，这篇论文讨论了会计的经济效应。会计政策工具效应可以一定程度上起到调节经济活动的作用。社会经济的发展受到国家的宏观调控，主要表现在货币政策以及财政政策两个方面，会计政策在财政政策中有着非常重要的作用。会计的政策工具效应主要是实现对成本、收入的调整，会计政策工具可以进行一定程度的调整，以保证其更好的满足经济周期方面的应用。

Accounting is a product of economic development, with the development of economy, the importance of accounting, accounting development on economic growth and promote the role of development, this is called the economic effect. With the rapid development of China's economy, accounting has a higher requirement, and the development and improvement of accounting have greatly influenced the economic development and reform.

The development of social economy directly leads to the change of accounting. The process of economic development belongs to the process of elaboration and coordination. In the process of economic development, social productivity has been steadily improved. In addition, with the development of economy, the existing economic model is constantly changing, which greatly promotes the elaboration of social division of labor.

In this stage of development, there is no clear division of labor, the producer and the consumer have the integration characteristics, in this case, there is no market. The main production purpose of the producer is to satisfy the needs of its own survival. The economy of this stage belongs to the closed state. People is both producers and consumers, in order to the production and consumption of products to record, store, and so on and so forth, people have a certain need to accounting, but because there is no clear division of labor and exchange mechanism, this stage of the accounting function is not significant, only record changes and other aspects of the product.

Products produced by producers on the one hand, not all used by producers themselves, on the other hand can't meet the demand of producers in other ways, based on this kind of situation, barter phenomenon appears, with its own products and others to carry on the exchange, products for your needs, meet the demand of its own survival. The emergence of the barter economy has led to a simple division of labor and a small market economy. People in a small market to complete bartering process, in this economic situation, accounting to recording changes in products on the one hand, also need to be the exchange of product changes for recording, at this stage there is an obvious change of accounting.

In the simple Commodity Exchange economy, money starts to appear, and producers can exchange their own products through money, and they can exchange their own products for money. In the social and economic situation, there is a simple division of labor, the size of the market to further expand, currency exchange phenomenon formed the model of equivalent exchange, further increased the demand for accounting.

In the era of developed Commodity Exchange, the production activities of producers are not only to meet their own needs, but also to obtain certain economic benefits. Therefore, the actual Commodity Exchange depth increasing, the division of labor is more detailed, the size of the market to further strengthen, in this case, the collaborative difficulty is very big, the role of accounting is more important.

The effect of accounting policy tool can adjust economic activity to some extent. The development of social economy is subject to the macro-control of the state, which is mainly reflected in monetary policy and fiscal policy. Accounting policies play a very important role in fiscal policy. Accounting policy tools effect is mainly realize the cost, the adjustment of income, accounting policy tools can be a certain degree of adjustment, to ensure its better satisfy the application of the economic cycle.

Resource allocation is mainly reflected in the market, capital in the capital market can realize effective flow between enterprises, and then realize the purpose of resource allocation. Resource allocation is the process of flow process of the capital, enterprise's operating results and financial condition can use accounting information to reflect directly, therefore, the enterprise's capital flow to a large extent affected by the accounting information.

In the social economic transactions, not only have retail market, and the content of financial market transactions, and can provide all the trading information, accounting information has a very important role and status.

The social division of labor exists not only between the production subjects, but also between different production areas. Through different ways of division of labor, can significantly enhance the efficiency of production management and professional, separate the business personnel and business owners, can better realize the enterprises of experts and professional management. The separation of two rights, can significantly improve the actual production capacity of enterprises, promote social progress and improve the productivity, but in terms of business information, still need to give priority to with the accounting information.

Accounting language can be regarded as a general commercial language, in order to strengthen the accounting economic effect, the need to make the accounting language unity guaranteed, you also need to go in the direction of the internationalization development. Through accounting language universality and can realize different countries, different regions between enterprise financial situation analysis, to improve the development of the economy as a whole has a very important role and significance. Using accounting language, regional, national economic comparison between different enterprises, can timely find problems and defects existing in the process of development of enterprise, formulate corresponding measures and methods, for policy makers to make appropriate decisions and the system to provide important reference to promote the development of enterprises.

Enterprise accounting information can directly reflect the actual operating conditions of the enterprise, only guarantee the authenticity of accounting information, to after all provide important reference for the establishment of decision-making and system indicators. In order to ensure the authenticity of accounting information, the accounting information management can be conducted in the way of enterprise accounting disclosure, and once the false information is found to be severely punished.

Belongs to a kind of business language, accounting information users need to have a comprehensive understanding, only to have a comprehensive understanding of specific accounting information, and understand the accounting information of all kinds of connotation and meaning of the expression, the economic effect of accounting fully show, want to make the accounting information more easy to understand, can be done from two aspects, on the one hand, strengthen the accounting education training, on the other hand enhance the generality of accounting information.

The resource allocation effect of accounting will gradually increase with the openness of accounting information, and the more people use it, the lower the cost of accounting transaction. Therefore, increasing the openness of accounting information can not only promote the economic effect of accounting, but also promote the development of social economy to some extent.

Accounting information has different USES for different users, so different accounting information needs to be different. Accounting system can optimize the resource allocation of the enterprise, to help enterprises better, reduce the risk of production and operation process in various vexed, when corporate managers when making decisions, by accounting information can guarantee the correctness and effectiveness of decision making. Therefore, different enterprises, when making the accounting system, need to combine their actual situation to promote the development of enterprises to achieve the system formulation.

Want to enhance economic benefits of the accounting, first of all need to strengthen the accounting language universality, secondly to ensure that the accounting information authenticity, also need to improve the popularity of accounting information, strengthen the accounting information disclosure, finally to make a set of accounting system, combined with the actual, in turn, better? L wave the value of accounting and promote the development of enterprises.

Essay代写：Museum culture

下面为大家整理一篇优秀的essay代写范文- Museum culture，供大家参考学习，这篇论文讨论了博物馆的文化。博物馆是历史文化的一部分，几乎每个城市都有一个代表当地文化特色的博物馆，因此，博物馆也就成了每个城市展现历史最为直接的一种表现形式。博物馆不仅有历史文化的记录，还保存着这些文化的最具代表的物品。现代社会，通过对当地博物馆的了解，可以加深人们对于文化特色的理解，对精神文明的加深，所以博物馆已经成为人们了解城市文化不可替代的地方。

The museum is a unit of research and protection, according to the museum's constitution. The purpose of the museum is to provide research, material evidence and cultural characteristics. Through the dissemination of people, to promote the purpose of historical culture. China is a has 4000 years civilization of the ancient civilizations, is humongous, absolutely not, but the real continues from the past until now, therefore, at every stage, must leave a different footprint, this needs us by confirming the museum of cultural relics to understand this period of history and culture, different regions, different times, cultural characteristics is also different. At present, people's understanding is not enough for the museum, but with the development of the society, people for the understanding of the history and culture is gradually deepened, to the role of the museum has a new look forward to.

People are eager to understand the footprints of history, to see what has happened, to go back to the past, but also to the expectation of the future. So in the transformation of the city development, the museum is bit by bit in the embodiment of spiritual civilization, the museum has become a civilization open a window, through the history to see nature, for the image of the museum, is a symbolic meaning.

In today's people pay more attention to spiritual civilization life, museum became people's spiritual home, in a museum, can feel the charm of different cultures not only, also can get a passion for the life in spirit, make people's heart toward a higher level of development, cultural heritage is a place of spiritual civilization, has a long history, every place has its own unique spiritual civilization, the museum collection exhibition on the history of the things, is a kind of culture. With the change of society, the cultural atmosphere of the city is changing, and people need spiritual support to purify the mind. Museum has an irreplaceable role in this respect, to give the burden of humanistic concern, the construction of healthy ecological museum, promote people's spiritual and cultural needs, building a harmonious spiritual home.

Culture need to record, demonstrated to heritage and cultural relics, cultural characteristics of the city lies in the inheritance and protection of cultural relics, first of all reflected in the protection of historical sites, and then to folk art and culture, local conditions and customs, folk art heritage, finally is to all art culture and the preservation of cultural relics, embodied in the museum. The existence of the museum has solved the phenomenon of cultural relics and cultural loss. It is the historical truth that has been preserved and presented to the people in full. Science team of archaeological discovery, collection of folk art, or spread of the treasures of the royal family, will become a museum collection of objects, because each has its special cultural connotation, is our predecessors left precious collections. It has a particular meaning. Reflecting the development of the local history and culture, the museum is a collection of these cultural heritages, which has a long history and is an important carrier to record the overall development of urban history and culture. Museums can influence the distant and profound history and culture of the city, great social wealth and human intelligence, which are incomparable in other parts of a city.

As an important part of the history and culture of the city, the museum has guided the audience to trace the ancient times clearly from the source through effective exhibitions and propaganda. A good museum, through the cultural relics, modern technology such as photography, acoustics, photoelectric, can fully show a certain historical period of culture in front of us, according to the characteristics of The Times, seize the typical changes of the history of the city, to the audience a vivid and stretch of the city "stories", in the process of visiting museums, to a major event in the history of leave deep impression.

Culture and cultural relics all need the protection of people, the museum is to manage human remains down items, show is to read part of the history museum, museum of history and culture protection is not only reflected in the cultural relics, such as material, also includes intangible cultural heritage, although there is no real existence, in this kind of art can be retained, can be read when people visit, feeling the non-material culture in the local folk how development, heritage museum is not directly involved in the life, but to shoulder the collection and preservation of intangible cultural heritage "carrier" responsibility, and have a lot of records. We will carry out in-depth research on the connotation of cultural heritage with historical data and relevant cultural relics professionals, and promote the inheritance of cultural heritage. At the same time, the museum can serve as a protection base for some important cultural relics.
