Factors Affecting CPU Performance Flashcards
1

A
It’s the time taken for one clock cycle to complete. If it takes a long time, it makes performance slow.
2
Q

Cache memory is the CPU’s on board memory. Instructions fetched from main memory are copied to cache and are quick to access if needed again. Unused instructions are replaced as cache fills up.
