Cycle per instruction คือ

In 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. See more The average of Cycles Per Instruction in a given process is defined by the following: $${\displaystyle CPI={\frac {\Sigma _{i}(IC_{i})(CC_{i})}{IC}}}$$ Where $${\displaystyle IC_{i}}$$ is the number of … See more • Cycle per second (Hz) • Instructions per cycle (IPC) • Instructions per second (IPS) • Megahertz myth • MIPS See more Let us assume a classic RISC pipeline, with the following five stages: 1.
