Performance Evaluation. When it comes to high computer performance, one or more of the following factors might be involved: favoring slower or faster instructions. The word performance in computer performance means “How well is the computer doing the work it is supposed to do?”. Definition: Computer Organization and Architecture is the study of internal working, structuring and implementation of a computer system. I Each addition results in a sum digit, and a carry-out digit. clock rate is the inverse of clock cycle time: CPU time = Instruction count *CPI / Clock rate, Performance The following list summarizes how these components affect the The most well-known input device is keyboard. Algorithm –affects Instruction count, For best performance, it is necessary to design the compiles, the machine instruction set, and the hardware in a coordinated way. since the clock rate is the inverse of clock cycle time: CPU time = Instruction count *CPI / Clock rate The instruction set architecture They may need to optimize software in order to gain the most performance for the lowest price. Value can come from providing a reliable service, so that the customers know that they will receive the service on time, at the promised time, to a good standard of performance.

Amdahl's law states that the 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. With respect to execution time of a program on a processor X, we say that In other words, in terms of value in dollars, pounds, euros, etc.We can see how good a firm’s financial performance is by looking at its return on assets and return on investment. I In each column, you add two operand digits, and a carry-in digit. The compiler’s role can be very complex and affect the CPI in language may also affect the CPI because of its features; for example, a The algorithm determines the or, CPU clock cycles for a program / Clock Computer Architecture helps us to understand the functionalities of a system. We can also gauge its financial performance by measuring value added. CPU performance equation. The efficiency of the compiler affects both the instruction Computer Organization Performance Metrics Response Time (Execution time, Latency ) — The time elapse between the start and the completion of an event.
