Question: Excluding some instructions from entering the cache can reduce conflict misses. a. Sketch a program hierarchy where parts of the program would be better excluded

Excluding some instructions from entering the cache can reduce conflict misses.

a. Sketch a program hierarchy where parts of the program would be better excluded from entering the instruction cache. (Consider a program with code blocks that are placed in deeper loop nests than other blocks.)

b. Suggest software or hardware techniques to enforce exclusion of certain blocks from the instruction cache.
