Consider a CPU that executes at a clock rate of 200 MHz(5ns per cycle) with a single level cache.
CPI execution i.e. CPI with ideal memory is 1.1.
Instruction mix are 50% arithmetic/Logical, 30% load/store, 20% control instruction.
Assume the cache miss rate is 1.5% and a miss penalty of 50 cycles.
1.The number of times cpu with ideal memory is faster when no miss occurs ?
2.Now,on doubling the clock rate to 400 MHz,How much faster is this machine,assuming similar miss rate,instruction mix as give above ?
