Question

Use the information given to solve part B

b. What is the speedup provided by Machine B over Machine A?

Consider two different machines A and B, with two different instruction sets. Machine A has a
clock rate of 200 MHz while Machine B has a clock rate of 4 GHz.
Assume a given program of 4 million instructions is being executed on both machines A and B.
The program consists of four major types of instructions. The instruction mix and the CPI for
each instruction type are given below:

Expert Solution

Step 1: Introduction

The average CPI is defined as the sum of each instruction multiplied by the fraction of time that instruction is used.

MIPS rate or Million instructions per second is the number of instructions that a CPU can process in 1 second.

Execution time is the time taken by the CPU to execute a set of instructions.
