Calculation of Average CPI in Percentage
Average CPI is calculated by taking the weighted average of the CPI values of each instruction based on their frequency. The formula for calculating average CPI is:
Average CPI = (Σ (CPIi * Fi)) / Σ Fi
Where:
- CPIi is the CPI of the ith instruction
- Fi is the frequency of the ith instruction
Example:
Let's consider a set of instructions with their respective CPI values and frequencies:
Instruction 1: CPI = 1, Frequency = 20
Instruction 2: CPI = 2, Frequency = 30
Instruction 3: CPI = 3, Frequency = 10
To calculate the average CPI, we will first multiply the CPI of each instruction by its frequency:
(1 * 20) + (2 * 30) + (3 * 10) = 20 + 60 + 30 = 110
Next, we will sum up the frequencies:
20 + 30 + 10 = 60
Now, we can plug these values into the formula:
Average CPI = 110 / 60 = 1.83
Therefore, the average CPI for this set of instructions is 1.83, which indicates the average number of clock cycles required to execute an instruction.
