2. Computer A has an overall CPI of 2.5 and can be run at a clock rate of 900 MHz. Computer B has a CPI of 4.5 and can be run at a clock rate of 1200 MHz. We have a particular program we wish to run. When compiled for computer A, this program has exactly 30,000 instructions. How many instructions would the program need to have when compiled for Computer B, in order for the two computers to have exactly the same execution time for this program?

EE344 Homework 1 1. Assume a color display using 8 bits for each of the primary colors (red, green, blue) per pixel and a frame size of 1280 × 1024. a. What is the minimum size in bytes of the frame buffer to store a frame? b. How long would it take, at a minimum, for the frame to be sent over a 100 Mbit/s network? 2. Computer A has an overall CPI of 2.5 and can be run at a clock rate of 900 MHz. Computer B has a CPI of 4.5 and can be run at a clock rate of 1200 MHz. We have a particular program we wish to run. When compiled for computer A, this program has exactly 30,000 instructions. How many instructions would the program need to have when compiled for Computer B, in order for the two computers to have exactly the same execution time for this program? 3. Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (class A, B, C, and D). P1 with a clock rate of 2.5 GHz and CPIS of 1, 2, 3, and 3, and P2 with a clock rate of 3 GHz and CPIS of 2, 2, 2, and 2. Given a program with a dynamic instruction count of 1.0E6 instructions divided into classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D, which implementation is faster? a. What is the global CPI for each implementation?
