Frequently Asked Questions
CPI stands for Cycles Per Instruction. It is the average number of clock cycles per instruction for a program or instruction mix.
Average CPI is calculated as the weighted sum of each instruction type's CPI multiplied by its frequency (as a decimal), i.e., Σ (CPI_i × Frequency_i) / 100.
Lower CPI generally means faster execution, but overall performance also depends on clock rate and instruction count.
