Suppose a computer using direct mapped cache has 232 words of main memory, and a cache of 1024 blocks, where each cache block contains 32 words. How many blocks of main memory are there? What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag, block, and offset fields? To which cache block will the memory reference 0003101A16 map?
