32 bytes of memory. 16 bytes of 2-way set-associative cache, where blocks can go anywhere within the set. Block is 2 bytes, set in cache is two blocks. Populate memory starting with upper-case letters, then 0-5. Hint- with full associativity in the set: each block has its own set of Tag bits in the cache. Memory is not organized by sets, though blocks get assigned to sets, and load in the cache per set. 1) Break down the addressing: Tag...

Assume the cache can hold 64 kB. Data are transferred between main memory and the cache in blocks of 4 bytes each. This means that the cache is organized as 16K=2^14 lines of 4 bytes each. The main memory consists of 16 MB, with each byte directly addressable by a 24-bit address (2^24 =16M). Thus, for mapping purposes, we can consider main memory to consist of 4M blocks of 4 bytes each. Please show illustrations too for all work. Part...
