C1. Assume a cache of 1 MB organized as 32 bytes each line. The main memory is 256 MB. [6 marks] 2. Determine the number of blocks in main memory (1.5 marks] b. Determine how to split the address (s-r, r,w) for direct mapping. (1.5 marks] c. Determine how to split the address (s, w) for associative mapping.[1.5 marks] d. Determine how to split the address (s-d, d, w) for set-associative mapping. Assume each cache set is 4 lines of the cache. [1.5 marks] C1. Assume a cache of 1 MB organized as 32 bytes each line.
