This is equivalent to an entirely sequential program and hardly employs any parallelism. 2. MISD : Multiple Instruction-Single Data No significant applications apart from systolic arrays have been devised for this kind of architecture and therefore this classification is rarely used. 3.

Comparing DEC Alpha and Intel Pentium Processors The main difference between the architectures of Digital Equipment Corporation's (DEC) Alpha and Intel's Pentium processors are the instruction sets. In this paper I intend on defining both RISC and CISC processors. In doing this I will be comparing DEC's Alpha 21164 (a microprocessor that implements the Alpha architecture) and also Intel's Pentium processors (from the Pentium-R through the Pentium II). Reduced Instruction Set Computing or RISC
instructions that extend the x86 instruction set of approximately 80; it has 32 KB of on-chip cache, verses the non-MMX on-chip cache of 16 KB, which enhances performance of even non-MMX applications, and it makes use of Single Instruction Multiple Data (SIMD) for more efficient data processing. The 57 new and powerful instructions are specifically designed to process and manipulate audio, video, and graphical data much more effectively. Intel, having doubled its on-chip cache size from 16 KB on non-MMX
GPUs and CPUs are used in a variety of computer systems. They can be used to even view the heavens. They are what enable us to send messages halfway across the world in a matter of milliseconds. They are the reason why science is as advanced as it is today. In modern society, teenagers rely on the CPU for the internet. It is a source of entertainment, social networking, homework help, and even sometimes friendships. Many adults use the GPU and CPU to write documents, to use email, paychecks, social
1. Introduction When it comes to computation speed, GPU provides a huge edge over the CPU making the GPU one of the most interesting areas of research in the field of modern industrial research and development. GPU is a graphical processing unit which enable you to run high definitions graphics on your personal computer, which are the demand of present day computing. Like the Central Processing Unit (CPU), it is a single-chip processor. However, the central processing unit, at latest, has 4 or 8

with single computer and it is the requirement to move on Parallel Computing to solved multiple task at the same time. 3.1 Flynn’s Taxonomy According to Flynn’s Taxonomy Parallel Computing Architecture is divided into four types: SD MD SI SISD SIMD MI MISD MIMD Single Instruction Single Data
mathematical calculations that are associated with graphics rendering. GPUs can be classified, using Flynn’s taxonomy, under the single instruction, multiple data streams, or SIMD, classification of computer architectures. Generally, most common CPUs can be classified as single instruction, single data stream or SISD. Commonly SIMD is faster but less diverse, SISD is likely slower but more diverse. Thus it is often worthwhile to run certain tasks on a GPU rather than a CPU, rather graphics based or
Windows vs. Macintosh Windows based computers are more practical, easier to use, and more versatile than Macintosh computers. There has always been much debate over which is the better system. There are people who are die-hard Macintosh users, and there are people who are the complete opposite, and naturally people sitting somewhere in between. The fact remains that the majority of home and business users own Windows based systems because of their versatility in all areas. More Practical
Technology extension to the Intel Architecture is designed to accelerate multimedia and communications software running on Intel Architecture processors (Peleg and Weiser). The technology introduces new data types and instructions that implement a SIMD architecture model and is defined in a way that maintains full compatibility with all existing Intel Architecture processors, operating systems, and applications. MMX technology on average delivers 1.5 to 2 times performance gains for multimedia and
bus, while Intel’s chips still ran on a 66mhz bus, this made AMD’s chip faster. It also was nearly 16% cheaper than any Intel based Pentium!! computer. The gaming community accepted the k6-2 with cautious, but open, arms. With their new SIMD-Enhanced (Single Instruction Multiple Data) 3Dnow! the graphics this processor were able to produce were amazing, for the time, due to the use of floating point intensive programs. With the new processor and their own design they were not only keeping
Commercialization of Personal Computers The IBM 5150, IBM’s first personal computer was introduced in a marketing campaign that led to more than 25 million Americans owning computer by 1987 (Smith and Alexander 15). IBM focused on educating consumers on how personal computers could be used to transform lives. The introduction of various applications including word processing, spreadsheet and database management facilitated information management and this led to the acceptance of personal computers

Strength of an organisation mostly depends on the management team. Without it, the organisation will go haywire. The people who run the management teams are called managers. "Management involves coordinating and overseeing the work activities of others so that their activities are completed efficiently and effectively" (Robbins et al., 2009, p.10). The manager interviewed is Mr. W and works for a small company, Neoncrafts Sdn Bhd. It has been established since January 1993. He holds the top-level
CHAPTER 1 INTRODUCTION 1.1 Motivation The performance of the single core processor has hit the wall because of power requirements and heat dissipations. Then Hardware industry started creating multicore CPUs. Although, they can compute millions of instructions per second, there are some computational problems that are so complex that a powerful microprocessor needs years to solve them. To build more powerful microprocessors requires an expensive and intense production process. Some computations
Comparison essay amd vs intel English III Throughout personal computer history there has been a monopoly on processors that company is Intel but that is changing by the day. There is a processor called AMD (advanced micro devices) currently leading in the silicon race for the fastest processor at an affordable price. No longer shall Intel lead the market when AMD makes its name superior. A CPU is a microprocessor that is generally constructed with millions of tiny switches called transistors
