Your cache has a hit time of 1 clock cycle and a miss time of100 clock cycles. If the CPI of your processor equals 1.3 withperfect caches (the cache always hits), then what is the CPI ifyour cache hits 71% of the time? Fill in the blank and show yourwork.

Your cache has a miss penalty of 50 clock cycles and a hit timeof 1 clock cycle. If your processor has a CPI of 1.5 with a perfectcache (it always hits), then what is your CPI if your cache alwaysmisses? one of them is correct.
Multiple-level caches are used because they?
a. provide a balance between low hit time and low miss rate.
b. have a higher combined hit rate than a single-level cache ofthe same size.
c. remove the need for a secondary memory.
