Assume for a given processor the CPI of arithmetic

Problem 2.46

Assume for a given processor the CPI of arithmetic instructions is 1, the CPI of load/store instructions is 10, and the CPI of branch instructions is 3. Assume a program has the following instruction breakdowns: 500 million arithmetic instructions, 300 million load/store instructions, 100 million branch instructions.

                                                            Step by Step Solutions

Step 1 of 2

Given,

        CPI of arithmetic instructions = 1

        CPI of load/store instructions = 10

        CPI of branch instructions = 3

Also, the instruction breakdowns are:

        500 million arithmetic instructions

        300 million load/store instructions

        100 million branch instructions
