1. How many total bits are required for a 2-way set-
associative cache with 16 KB of data and 16 B
blocks, assuming a 32-bit address, LRU replacement
policy, and write-back policy?
2. Consider a system with 2 level cache. Level 1
cache, Level 2 cache, and main memory access
times are 2 ns, 11 ns, and 500 ns respectively. Level
1 and Level 2 cache hit rates are 0.8 and 0.9,
respectively. Find out the average memory access
time of the system.
