Let's pretend that something unexpected happens: the CPU makes a partially-completed request to the cache at the same time as a block is being returned from the write buffer to main memory. The following steps need to take place.

This chapter explains how to implement the four cache replacement policies.

Given that a 4-way set associative cache memory has 64 KB data and each block contains 32 bytes. The main memory capacity is 4 GB. a. Find the number of bits for the main memory address. ANSWER: bits b. How many blocks are there in a set? ANSWER: blocks c. How many sets the cache has? ANSWER: d. The main memory address format is => | Tag: e. Which set will be mapped by the main memory address 458195h. ANSWER: sets bits | Set: bits | Word: bits | (in decimal)
