Melano Previous slide: Next slide: Back to first slide: 2 MIPS and MSUs are both highly imperfect relative measures of capacity for an IBM Mainframe system.
how to calculate cpi, mips and execution time Since the MIPS measurement doesn't take into account other factors such as the computer's I/O speed or processor architecture, it isn't always a fair way to measure the performance of a computer. More on this later, when we discuss pipelining. It is the multiplicative inverse of instructions per cycle. It can be said that the processing power of a computer increases the faster the CPU performance. WebExecution time = 1.0109 3.7 0.510-9sec = 1.85 sec.
It is used to gauge inflation and changes in the cost of living. CPU execution time = = CPU clock cycles x Clock cycle. * The five major computers including the CPU are summarized in the following article. For example, if a computer has four processors and it takes 5 seconds to execute a task, then the number of MIPS is (5/4) = 1.25 (or 25%).
