-
- Illustrate a multi-level memory hierarchy, including typical sizes and speeds of access.
- Suppose that in 1000 memory references there are 40 misses in the first level cache and 20 misses in the second-level cache. What are the various miss rates? Assume the miss penalty from L2 cache to memory is 100 clock cycles, the hit time of L2 cache is 10 clock cycles, the hit time of L1 is 1 clock cycles, and there are 1.5 memory references per instruction. What is the average memory access time and average stall cycles per instruction? Ignore the impact of writes.
-
