Cpi per instruction

WebCycles per instruction, or CPI, as defined in Fig. 14.2 is a metric that has been a part of the VTune interface for many years. It tells the average number of CPU cycles required to retire an instruction, and therefore is an indicator of how much latency in the system affected the running application. WebIn computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor’s performance: the average number of clock cycles per instruction for a program or program fragment. It is the multiplicative inverse of instructions per cycle.

WebClocks Per Instruction. Clocks per instruction (CPI) is an effective average. It is averaged over all of the instruction executions in a program. CPI is affected by instruction-level parallelism and by instruction complexity. Without instruction-level parallelism, simple instructions usually take 4 or more cycles to execute. WebCPI is affected by instruction-level parallelism and by instruction complexity. Without instruction-level parallelism, simple instructions usually take 4 or more cycles to execute. Instructions that execute loops take at least one clock per loop iteration.
