The Classic CPU Performance Equation in terms of A high performance computer is designed to go fast, and its organization and semantics are specially devised to deliver computational speed. I In each column, you add two operand digits, and a carry-in digit. 2 0 obj For example, if the algorithm uses more 1.5.1. In computing, computer performance is the amount of useful work accomplished by a computer system. <>>> Computer Organization Performance Metrics Response Time (Execution time, Latency ) — The time elapse between the start and the completion of an event. favoring slower or faster instructions. floating-point operations, it will tend to have a higher CPI. depends on the algorithm, the language, the compiler, the architecture, and the The primary factor when you’re looking at computer performance is time. indirect calls, which will use higher-CPI instructions. 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. or. clock rate is the inverse of clock cycle time: CPU time = Instruction count *CPI / Clock rate, Performance Organization performance can also be described by evaluating the reliability of service and by understanding the quality of customers of the organization. 2. 4.
