fast memory block known as Instruction cache. The reason for using small and fast memory is to reduce latency. Instruction cache also stores recently executed instructions making the instruction fetch more efficient. All the instructions to be fetched are stored in this memory and are fetched by the program counter. Program counter is used to search the instructions. If the desired instruction is found, then it is termed as cache hit or else it is a cache miss. We all are familiar that superscalar
A Tour of the Pentium Pro Processor Microarchitecture Introduction One of the Pentium Pro processor's primary goals was to significantly exceed the performance of the 100MHz Pentium processor while being manufactured on the same semiconductor process. Using the same process as a volume production processor practically assured that the Pentium Pro processor would be manufacturable, but it meant that Intel had to focus on an improved microarchitecture for ALL of the performance gains. This guided
against competition and identify new opportunities. In computing, a cache is a component that stores data so future requests for that data can be served faster; the data stored in a cache might be the results of an earlier computation, or the duplicates of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot. Cache hits are served by reading data from the cache, which is faster than recomputing a result or reading from a slower
allows continued execution for instructions that use both the memory access pathway and the arithmetic pathway in the event that the data cache misses, this means that the requested data was not in the cache and had to be accessed in the data memory. The pipeline can also take alternate paths for different memory operations. Using a direct mapped 128 entry cache, which stores previous branch instructions, the pipeline can make targeted address, or dynamic branch predictions. This means it fills the
Mathematics has always been a necessary component in modern warfare. During the World War II era, mathematicians Alan Turing and John von Neumann were responsible for some of the technological and scientific developments which contributed Allied victory. After considering their accomplishments before the war, their contributions during the war, and how they were recognized after the war, you will see that each mathematician is remembered very differently for their contributions. Turing is barely
today like C, C++ and Java. Since when I was introduced to the world of computer programming, I could see the minute similarities between the languages and could translate almost any program from one to another. My extraordinary skill in writing algorithms helped me in working for a project titled ‘Hotel Management using C++’ during the event ‘Insight 2009’ which was conducted by Tata Consultancy Services. After the project, I wanted to extend my field of expertise beyond the world of programming
approaches to produce greater results with reduced resources (space, time). To answer the questions like Can something be efficient, yet small, easy and still perform herculean tasks. My area of interest is the study and contribution towards field of algorithms and optimized solutions. So I will undertake postgraduate study in Computer Science in Stony Brook University. To achieve this I plan to study the relevant disciplines which will enable me to accomplish what I desire. In my work experience and academics
Personal Statement MS in Computer Science, University of Illinois Being naturally intrigued about Computers, I pursued my undergraduate studies in Computer Science and Engineering at College of Engineering Trivandrum, University of Kerala, India. I intend to do my higher education in Computer Science and would like to get enrolled into the Masters Program at University of Illinois at Urbana-Champaign starting Fall ‘14. My Interest in science started in early childhood. I was fascinated by
WHY STUDENTS CHOOSE TO STUDY COMPUTER SCIENCE Introduction Computer Science is the study of Computer theory, experimentation, designs and engineering. Studying computer science has always been my dream. From the first time I sat in front of a computer, I have always wanted to know how computer work, how software could make hardware do what it does, I did research and discovered a lot about computer science. With what I found about computer and the opportunities I holds I decided to study it and hopefully
The career path that I have chosen was computer engineering. I chose this career because I have spent my entire life around computers, and had experience working with programming languages and the hardware. I gained further interest in computer engineering after I took an AP Computer Science class in high school. In the class I was required to use programming languages to create different types of programs which challenged me. This inspired me to want to learn even more about the computer science
With my intentions firmly in place to gather both sound knowledge and expertise in the field of Computer Science at the Master’s level, I am on the look out for the best education I can avail in CS at this phase. I am intrigued, deeply fascinated and motivated by the latest trend for convergent sciences and technical developments. This has made technical applications even more versatile and utilitarian in the world. With the fact that pure sciences are now blurring and finally being accepted as one
United States Bureau of Labor Statistics, “Computer and information research scientists create and improve computer algorithms, which are sets of instructions that tell a computer what to do.” (United States Bureau of Labor Statistics) They go on to say that some tasks done on a computer are very difficult and require complex algorithms. Research scientists try to simplify these algorithms to make computer systems as efficient as possible. (United States Bureau of Labor Statistics) So where Bobby works
“Go confidently in the direction of your dreams. Live the life you have imagined.” This is the principle that I follow throughout my life. I have always aspired to choose a career that would mean work that really simulates me and holds a natural appeal for me. Advances in Computer and Information Technology over the past few decades have brought about revolution in science, medicine, education, business, and entertainment. I wish to be part of the future revolution and that is why I want to study
Abstract : In this research paper, I will give you an abstract level of familiarization with Hyper Computation. In my work, I will give you an introduction about hyper computation and then relate the hyper computation with turing machine. Later in this research paper, we analyze different hyper machines and some resources which are very essential in developing a hyper computing machine, and then see some implications of hyper computation in the field of computer science. Introduction (Hyper

Availability of any method of exhaustive (complete) search, e.g. «British museum algorithm», is quite enough for Logic (logical form). On the other hand, the process of «problem-solving» can be investigated in the light of the following question: «how is it possible to build a piece of correct reasoning?». This task is considered in
Alan Turning: A Sad Mystery “The original question, ‘Can machines think?’ I believe to be too meaningless to deserve discussion. Nevertheless I believe that at the end of the century the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to be contradicted…. The popular view that scientists proceed inexorably from well-established fact to well-established fact, never being influenced by any improved conjecture
