a. Assume we need to design four caches with different mapping methods. The cache consists of eight one-word blocks. One cache is fully associative, a second is two-way set-associative, the third is four-way set associative, and the fourth is direct-mapped. Find the number of misses for each cache organization given the following sequence of block addresses: 0, 16, 0, 6, 16, 6, and 14. What is the hit rate in each design?

b. Assume a cache of 16 blocks, a 8 word block size and a 32-bit address. Please tell the total numbers of sets/blocks, and the total number of tag bits for caches that are direct mapped, two-way and four-way set associative, and fully associative.
