2. (30 points) For each of the following memory hierarchies, calculate the average memory access time. If you end up with a fractional number of cycles, round up there isn’t much you can do (besides read/write the register file) in half a cycle! a. The cache takes 1 cycle to access and has a 15% miss rate, main memory takes 250 b. The cache takes 3 cycles to access and has a 95% hit
