When a cache is 10 times faster than main memory , and cache can be used 90% of the time , how much speed we gain by using cache ? |

Answer» ██████████████████████████ ━━━━━━━━━━━━━━━━━━━━━━━━━ = ((2P/10) * 100) + ((8P/10) * 1) = (208/10)P nanoseconds. Thus speed up will be AROUND 4.8(less than 5 but near 5), assuming the CACHE is 100 TIMES FASTER than main memory ━━━━━━━━━━━━━━━━━━━━━━━━━ ━━━━━━━━━━━━━━━━━━━━━━━━━
