Calculation of CPI (Cycles Per Instruction). For the multi-cycle MIPS. Load. 5 cycles. Store. 4 cycles. R-type. 4 cycles. Branch. 3 cycles. Jump. 3 cycles. In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: CPU Time = I * CPI * T. I = number of instructions in program; CPI = average cycles per instruction; T = clock cycle timeThe three factors are, in order, known as the instruction count (IC), clocks per instruction (CPI), and clock time (CT). CPI is computed as an effective CPI per core is fairly straightforward as shown in Fig. 14.3. To calculate an “Aggregate” CPI, or Average CPI per core, divide the sum of all core's threads
