The CAMERA simulator using 2-way associative cache has 256 bytes (i.e. 28 bytes) of byte-addressable main memory and a cache of 16 blocks, where each cache block contains 8 bytes.

a. How many blocks of main memory are there?

b. What is the format of a memory address as seen by the cache, that is, what are the size of the tag, set and word fields?

c. Given a 2-way set associative mapped cache memory in CAMERA and a main memory, the cache memory is empty initially and data is stored in the main memory, CPU sends a request to fetch the data stored at address 0x95 in main memory (i.e. fetch 95). Please fill up one of the cache blocks after CPU executes the fetch request?
