Question

we add an l2 cache (the earlier cache is the l1 cache), which has a hit time of 20 cycles. we run a program that exhibits an 80% l1 hit rate, and a 95% l2 hit rate (note that the l2 hit rate only counts accesses that miss on the l1 cache). our miss penalty is still the 100 clock cycles needed to access main memory. what is the amat for this cache setup on this program?

Answer 1

Answer:The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the highest-end Intel Core i9 use caches. Even higher-end microcontrollers often have small caches or offer them as options — the performance benefits are too large to ignore, even in ultra-low-power designs.
