1- Computer C1 has an overall CPI of 2.0 and can be run at a clock rate of 3 GHz. Computer C2 has a CPI of 2.5 and can be run at a clock rate of 5.5 Ghz. A particular program when compiled for Computer C1 has exactly one million instructions. How many instructions would the program need to have when compiled for Computer C2, in order for the two computers to have the same execution time for this program?

2- The CPU design team is designing an instruction set with three classes of instructions. Parameters are given in the following table. Consider a program with 65% ALU instructions, 25% memory access instructions, and 10% control instructions. What is the average CPI for this CPU?

3-  Write the following sequence of code into RISC-V assembler. Assume that x, y, and z are stored in registers x18, x19, and x20 respectively.

z = z + y - x - 4;
