Name three reasons why we use caches in a pipelined processor :

Solution

The use of cache memories solve the memory access problem. In exacting, while a cache is included on the same chip as the processor, access time to the cache is usually the same as the time needed to perform other basic operations inside the processor. Each stage in a pipeline is expected to complete its operation in one clock cycle. Hence, the clock period should be sufficiently long to complete the task being performed in any stage. The clock cycle has to be equal to or greater than the time needed to complete a fetch operation. However, the access time of the major memory may be as much as ten times better than the time needed to perform basic pipeline stage operations inside the processor, such as adding two numbers
