How do you calculate the cpi and mips?

The Cost Per Instruction (CPI) is calculated by dividing the total execution time of a program by the total number of instructions executed. The formula is: CPI = Execution Time / Instruction Count.

Meanwhile, MIPS (Million Instructions Per Second) is calculated by dividing the total number of instructions executed by the total execution time in seconds, then converting it to millions. The formula is: MIPS = (Instruction Count / Execution Time) / 1,000,000.
