Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. PerformanceAssessment In evaluating processor hardware and setting requirements for new systems, performance is one of the key parameters to consider, along with cost, size, security, reliability, and, in some cases power consumption. count and average cycles per instruction, since the compiler determines the It basically depends on response time, throughput and execution time of a computer system. This chapter introduces the basic foundations of computer architecture in general and for high performance computer systems in particular. Computer Organisation Functional Units:- A computer has five functionally independent main parts: Input Unit Memory Unit Arithmetic and logic Unit Output Unit Control unit Input Unit:- Computers accept coded information through input units, which read the data.

Notes on Calculating Computer Performance Bruce Jacob and Trevor Mudge Advanced Computer Architecture Lab EECS Department, University of Michigan {blj,tnm}@umich.edu Abstract This report explains what it means to characterize the performance of a computer , and which methods are appro-priate and inappropriate for the task. This can require quite a detailed analysis of the computer's organization. Throughput (Bandwidth) — The amount of work done in a given time. The computer system is formed when 2-3 parts combine and perform individually as well as coherently. 1. Using electronic communication like email, instant messaging and webcasts, organizational leaders can communicate with a very large number of employees in real time regardless of physical location. Response time is the time from start to completion of a task. To achieve Despite these underlying trends, the performance of computer systems has increased at a rate which technological approaches. Computer organization helps optimize performance-based products. For best performance, it is necessary to design the compiles, the machine instruction set, and the hardware in a coordinated way.
