A two-way set associative cache memory uses blocks of four words. The cache can accommodate a total of 512 words from main memory. The main memory size is 4096 x 16 bits. a) Formulate all information required to construct the cache memory. How many bits are there in TAG, BLOCK (row) and WORD (column) fields? b) If this writeback data cache is using LRU replacement policy, trace the execution of the following references by filling in the table.
