1. Q1 (10 marks) CPU Performance Show your work in the computation of the following questions A) Suppose you have two procesors with the following specifications: Processor 1 runs at 2.6 GHz and has a CPI of 1.4. Processor 2 runs at 3.9 GHz and has a CPI of 2.4 Which processor will perform faster? How much faster is the performance B) Consider the following situation - You are running a program on a 1.5GHz processor. - Your instruction set has two categories: Memory access instructions and non-memory access instructions Memory access instructions make up 23% of your program's instructions. Your miss rate for accessing instructions is 3% (The percent of time you have a cache miss when fetching any instruction) Your miss rate for accessing data is 30%. (The percent of time your memory access instructions result in a cache miss when accessing data) Every instruction takes 2 cycles to execute, not accounting for stalls due to memory accesses Your miss penalty is 60 cycles What is the average CPI for executing this program, when accounting for stalls from memory accesses! C) You are provided with the option to tune your cache's performance so that the miss rate for accessing data drops to only 10%, but due to holding more data in the cache at any given time you increase your miss rate for instruction fetches to 4% Which option is faster, leaving your cache as it was in part B, or choosing to tune it as above? How much faster is the faster option? Submit your answers in the file a3ql.txt XOR a3q1.pdf
