...Cache Memory [pic] – Study of large program reveal that most of the execution time is spend, in the execution of a few routines (sub-sections). When the execution is localized within these routines, a number of instructions are executed repeatedly, This property of programs is known as LOCALITY OF REFERENCE. – Thus while some localized area of the program are executed repeatedly, the other areas are executed less frequently. – To reduce the execution time these most repeated segments may be placed in a fast memory known as CACHE (or Buffer) Memory. – The memory control circuitry is designed to take advantage of the property of LOCALITY OF REFERENCE. – If a word in a block of memory is read, that block is transferred to one of the slots of the cache. Cache Operation: – CPU requests contents of memory location – Check cache for this data – If present, get from cache (fast) – If not present, read required block from main memory to cache – Then deliver from cache to CPU – Cache includes tags to identify which block of main memory is in each cache slot [pic] [pic] [pic] Fig: Cache Organization Elements of Cache Design: Cache Size Write Policy Replacement Algorithm Mapping Function Block Size / Line Size CACHE SIZE: – Size of cache should be small enough so that average cost per bit is close to that of main memory and large enough so that average access time...

...Computer Architecture Student’s name Professor Intro to Information Technology February 2, 2014 Computer Architecture John von Neumann published the Von Neumann architecture on June 30, 1945. The central processing unit (CPU), the memory, and the input/output devices (I/O) are the main three building blocks of the Von Neumann computer systems connected using the system bus. The components of the model are composed of memory, arithmetic logic unit (ALU), input/output, and the control unit. The memory is where all the data information is stored, in present computers it is call the RAM. The ALU is where the calculation and processing of information take place. The input gets information into the computer like the keyboard, and the mouse. The output gets information out of the computer like the monitor and the printer. The control unit makes sure that all other parts are doing their job correctly and on time. Modern computers still follow the idea of Von Neumann architecture. The CPU chip holds the control unit and the ALU and the memory in the form of RAM located on the motherboard. Von Neumann architecture is important in the present day. All modern computers are based on the same basic design. The central processing unit does the calculations, a memory to hold the data, and an interface that allows the input/output to change the information in memory. The architecture is simple and can be easily reduced to a smaller size and capacity needed. Back in 2012 at the University...

...2/3/2014 Week 4 Assignment 1 Computer Architecture John von Neumann was a mathematician and polymath who was born on December 28 1903 and while he made major contributions to a number of fields the one we care about in the IT field is von Neumann Architecture. In 1946 he co wrote a paper with Arthur W. Burks and Hermann H. Goldstine and out lined what would be need for a general purpose electronic computer. The title of the paper was “Preliminary Discussion of the Logical Design of an Electronic Computing Instrument” ( von Neumann , 2000) and the idea of the paper would have far reaching impacts on the field of computer science and would lead the design and building of the first computer call Manchester Mark I witch ran its first program in 1948. While the history lesson of the man is all well and good the question we need to ask ourselves is how the von Neumann architecture works and what goes into the process. Von Neumann believe that computing machines contained four parts the arithmetic logic unit this part of the architecture is solely involved with carrying out calculations upon the data such as adding subtracting multiplying and division the control unit will manage the process of moving data and program into and out of the memory and also deal with carrying out program instructions the memory that can hold data and also the program processing that data in modern computers this RAM and the input-output devices which allows for the idea that a person needs to interact...

A stored-program concept is the programming process could be facilitated if the program could be represented in a form suitable for storing in memory alongside the data. Then, a computer could get its instructions by reading them from memory, and a program could be set or altered by setting the values of a portion of memory. 2.2. The four main components of any general-purpose computer * Main memory (M) * I/O module (I, O) * Arithmetic-logic unit (CA) * Program control unit (CC) 2.3. The three principal constituents of a computer system at an intergreted circuit level * Transistors * Resistors * Capacitors 2.4. Explain Moore’s law The famous Moore’s law, which was propounded by Gordon Moore, cofounder of Intel, in 1965. Moore observed that the number of transistors that could be put on a single chip was doubling every year and correctly predicted that this pace would continue into the near future. To the surprise of many, including Moore, the pace continued year after year and decade after decade. The pace slowed to a doubling every 18 months in the 1970s, but has sustained that rate ever since. 2.5. The key characteristics of a computer family * Similar or identical instruction set: In many cases, the exact...

...Assignment 1: Computer Architecture Joseph Henry Strayer University CIS 106 Prof. Shaun Gray November 03, 2013 Assignment 1: Computer Architecture Von Neumann architecture is named after the late John Von Neumann, who was part of a team that created the EDVAC in 1944. This machine was the follow up to the ENIAC, simply because the ENIAC could not modify the program’s contents and could only hold 20 10-digit numbers at a time, needing to be programmed manually (Anderson, Ferro, & Hilton, 2011, p. 11) The concept of Von Neumann architecture is that of a stored program computer, where both binary instructions and data are stored on the main memory. Basically, a program is loaded into memory, and that program could modify itself and be written to perform other functions. Binary instructions are fetched at the same time that data operations occur since they share the same bus. From the computer’s memory, instructions are processed in order and executed by the central processing unit (CPU). The focal point is the CPU, which contains an arithmetic login unit (ALU), control unit (CU), and registers (small storage areas). The ALU performs mathematical functions, especially addition. The CU controls the data traffic in and out of the CPU. The registers are small high-speed units that store instructions and data for the CPU. The CPU accepts input and provides output to external devices. A crystal clock, known as the System Clock times each step in the fetch-execute cycle that...

...Have you ever wondered how using a computer actually accomplishes tedious tasks? Tasks including connection to the internet, moving a file from one location to another, or having the ability to use a video application that helps interact with family in remote locations. If the needs of a computer were adequate enough to produce one specific function, such as typing, than the technologies we have now would not exist. The computers of today need to perform expeditious data processing for extensive data tasks. That’s approximately three billion calculates per second on just your average household computer. (Tymann 2008). This is all accomplished by programmable chip sets known as central processing units. Programmable codes within the central processing units are known as complex instruction set computing and reduced instruction set computing. Technologies in the present and the future depend on these architectures for expedited growth, without them society will halt in technological advances. These computing architectures provide the foundations of computer processing, although each having their specific advantages, disadvantages, pros, and cons. Information technology is rapidly growing, providing users and businesses a means to share digital data. Businesses gear towards investing money in all aspects of information technology systems to provide services for their customers. Users use computers as a means to communicate with family or watch the latest movie over the internet...

...Abstract Computer architecture and its history are important to understanding how a computer works. The Von Neumann architecture is the basic building block to the modern day computer. There are different types of functions within the Von Neumann architecture that have helped create an efficient design and allow computers to perform multiple functions rather than being used for one specific purpose. The Von Neumann model uses memory, system buses, and Boolean operators to communicate programs and perform functions. Computer Architecture- Von Neumann Architecture Explained A computer is an electronic device that operates under the control of instructions that are stored in memory. The concept of storing memory or instructions within the computer came from John Von Neumann. Von Neumann architecture can be best described as a stored program design. A stored programmed design means that the program that operates the computer and the instructions that carry out the program are stored on the computer in one location, memory. By having a stored program design, the computer doesn’t have to go through a rigorous process to be reprogrammed, or to perform multiple functions. The basic design of today’s computers is founded on the architecture of Von Neumann, which can be referred to as the “fetch-execute cycle”. The Von Neumann model consists of five major components that work together to make the computer perform. There is an area for memory to be held and processed; today we know...

Finally, a short list of various types of computer storage and memory will be included, and a definition of computer storage. Keywords: Neumann, Boolean, Memory, Storage, System, Bus John Von Neumann was born in 1903 in Budapest. He studied mathematics and graduated from the Pázmány Péter University in Budapest with a Ph.D. In 1930 he was invited to the University of Princeton to teach mathematics in the Institute for Advance Study of Princeton. Von Neumann possessed an extraordinary memory, he was a gifted man that made multiple contributions to the math world, and the computer world, but perhaps his biggest contribution is the creation of the Von Neumann Architecture. The Von Neumann architecture stated that a computer was able to have an uncomplicated, established structure, able to execute any calculation when given the proper command. The Model of this architecture is comprised of the following components, the memory, the control unit, the arithmetic logic unit (ALU). The memory was used to store the information from the ALU or processing unit. This...

...Evolution of Computer Applications and Architecture By Ken Jacobi, Computer Architecture (IT-501) In discussing the evolution of computer architecture, we find that there are many angles on how people tend to view things. Some will take consideration in how things have changed over the last few years. Others will take a stronger look at the direction of where they believe technology is going. A third focus is in regards to the unexpected mistakes that people have made. In conjunction with the past, how can these mistakes be avoided in the coming future and evolution of technology; both for equal and competitive reasons. In part with this, we can turn to the very basic view about what makes a good design. Many architectural topics once began with the idea that if you build something and develop it correctly, change is not something one should expect. If it’s developed right the first time then you don’t have to change it. In this successful strive, people have come to the underlying conclusion that this is a very unrealistic position to be. A very good place to stress the relevance here is by dating back to the start of an exciting architectural turn of events that have gotten us to where we now are: the birth of modern computing. Many will say that this “landmark” of progress has lead to an evolutional launch that we constantly live within. It’s safe to say that these embarking events once began somewhere amongst the early 1970s. Coming out of the...

...NAME: BOLAJI ABIODUN FOLORUNSO COURSE: COMPUTER ARCHITECTURE. INTRODUCTION As computer architectures become increasingly complex, more sophisticated analysis methods and optimization tools are required to harness their full performance. Technologies such as event-based sampling and expert systems are now augmenting traditional methods of performance analysis based upon profile and call graph tools. Understanding the basics of performance analysis, as well as the current state- of-the-art software optimization technologies, enables developers to pinpoint and implement solutions to application performance issues. One sophisticated processor, the Intel® Pentium® M processor, is growing in embedded application usage due to its high performance and low power utilization. The Intel Pentium M processor features Intel MMX™ and Streaming SIMD Extensions (SSE, SSE2) that enable higher performance through parallel computation. Getting the most out of the processor, however, requires that developers take full advantage of these built-in performance enhancements. Software optimization technology offered by advanced compilers utilizes the enhancements in Intel Pentium M processors in a fashion conducive to embedded development. Compiler technology provides access to these extensions with low development investment while maintaining backward compatibility and minimal code size, two critical challenges in embedded software development. The key to focusing the optimization process...

It is not like a child who wants to know why the sky is blue, or why dogs can’t talk. A students real interpretation of the question why is more like: “Why is this important?”, or “Why do we have to learn this?”, or the big one (according to Algebra teachers), “Will I ever use this again in the real world?” A computer architecture professor is different from other professor (besides obviously being smarter ;) ), when having to answer this question. Unlike Algebra, which is pretty well established and unlikely to change operations in the next 10 years, Computer Architecture is a rapidly evolving industry and has the very good possibility to look completely different in the year 2022. So a computer architecture professor is faced with a difficult answer to the question. One answer could be “Yes you have to learn it, because it appears on the final and I will...
