EXERCISES

1.   ◆1. Suppose a computer using direct-mapped cache has 2²⁰ bytes of byte-addressable main memory and a cache of 32 blocks, where each cache block contains 16 bytes.

   1. a) How many blocks of main memory are there?

   2. b) What is the format of a memory address as seen by the cache; that is, what are the sizes of the tag, block, and offset fields?

   3. c) To which cache block will the memory address 0x0DB63 map?
