MIPS Calculation Formula

Explanation of MIPS calculation method is below.

MIPS

MIPS is a unit representing that 1 million instructions can be executed per second, which is expressed as 1 MIPS.

The number of instruction execution per second is obtained by dividing one second by the execution time of one instruction.

That is, the calculation formula is as follows.

Calculation Formula

  • MIPS = number of instructions executed per second ÷ 10 ^ 6
  • number of instructions executed per second = 1 second ÷ execution time of one instruction
  • execution time of one instruction = one clock time × CPI
  • one clock time = 1 second ÷ clock frequency.
  • CPI (Cycles Per Instruction) =  the number of instructions that is executed per clock.
