1. (8 marks) Suppose that the following clock cycles per instruction, and frequencies of usage by a particular program, have been determined for the four instruction types of a system with a clock rate of 2 GHz. Instruction type B C D Clock cycles per instruction Frequency 3 20% 1 40% 2. 30% 4 10% (a) What MIPS rating is achieved is achieved for this program on this system? What is the CPU (b) Suppose that 500 x 100 instructions are executed in total. execution time? (c) Suppose it was possible to replace particular pairs of type C instructions with single type A instructions. Would the MIPS rating increase, or decrease, with this change? (d) If it were possible to replace 2/3 of the type C instructions in the manner described in part (c), by what percentage would CPU execution time decrease? 1.
