Enter the total number of cycles and the total number of instructions into the Calculator. The calculator will evaluate the Clock Cycles Per Instruction.

## Clock Cycles Per Instruction Formula

CPI = C / I

Variables:

- CPI is the Clock Cycles Per Instruction (cycles/instruction)
- C is the total number of cycles
- I is the total number of instructions

To calculate Clock Cycles Per Instruction, divide the number of cycles by the number of instructions.

## How to Calculate Clock Cycles Per Instruction?

The following steps outline how to calculate the Clock Cycles Per Instruction.

- First, determine the total number of cycles.
- Next, determine the total number of instructions.
- Next, gather the formula from above = CPI = C / I.
- Finally, calculate the Clock Cycles Per Instruction.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total number of cycles = 6

total number of instructions = 7
