WebReducing Cycle Time Cycle time is a function of the processors design If the design does less work during a clock cycle, its cycle time will be shorter. By using the number of clock cycles required from the clock frequency and the CPI, the execution time of the instruction can be calculated. Cycle time is a function of process technology. Alternatively, divide the number of cycles per second (CPU) by the number of cycles per instruction (CPI) and then divide by 1 million to find the MIPS. *An estimate for 2021 is based on the change in the CPI from second quarter 2020 to second quarter 2021.
