    A direct-mapped cache consists of 8 blocks. Byte-addressable main memory contains 4K blocks of 8 bytes each. Access time for the cache is 22ns, and the time required to fill a cache slot from main memory is 300ns. (This time allows us to determine the block is missing and bring it into cache.) Assume a request is always started in parallel to both cache and to main memory(so if it is not found in cache, we do not have to...

    A 2-way set associative cache consists of four sets 0, 1, 2, 3. The main memory is word addressable (i.e. treat the memory as an array of words indexed by the address). It contains 2048 blocks 0 through 2047, and each block has eight words. (a) How many bits are needed to address the main memory? (b) Show how a main memory address will be translated into a tag, a set number, and an offset within a block. Illustrate this...

    Assume a memory model where you have a cache size of 4 blocks, a block size of 8, and addresses from 0 through 511. Assume that the n-way associative cache and fully associative cache use a LRU (least recently used) eviction strategy. Consider the following sequence of memory accesses: 17, 66, 22, 66, 80, 41, 85, 66, 17, 104. (a) Show the updates to a 2-way associative cache in a table using a similar format to the table shown on...
