Consider a system with a main memory access time of 50 ns supported by an L1 cache having a 5 ns access time and a hit rate of 90% and an L2 cache having a 10 ns access time and a hit rate of 80%. What is the average memory access time for a look aside cache? (include units) [Answer1] What is the average memory access time for a look through cache? (include units) [Answer2]

A processor has the following resource execution times: Instruction fetch : 250 ps Instruction decode and register read: 100 ps ALU : 100 ps Memory read/write: 250 ps Register write: 100 ps   If we use a single cycle datapath, what is the clock rate? Include units [Answer1]  If we operate a 5 stage pipelined datapath, what is the clock rate? Include units. [Answer2]  What is the speedup when executing 15 instructions on a 5 stage pipelined processor compared to a single cycle processor? There are no hazards and no stalls. [Answer3]
