A computer has a cache and main memory. 20 ns are required to reference a word that is in the cache. If the word is in main memo
Alecsey [184]

Answer:

T_{average} =12026ns

Explanation:

Given Information:

T_{cache}=20 ns

T_{main}=60ns

T_{disk} =12ms=12,000,000ns

hit_{cache} =0.9

miss_{cache} =1-0.9=0.10

hit_{main} =0.99

miss_{main} =1-0.99=0.01

There are 3 possible cases

1. Location of reference word is in cache

T_{cache}*hit_{cache} =20*0.9=18ns

2. Location of reference word is not in cache but in main memory

(T_{cache}+T_{main})*(miss_{cache}*hit_{main}) =(20+60)*(0.10*0.99)=7.92ns

3. Location of reference word is neither in cache nor in main memory

(T_{cache}+T_{main}+T_{disk})*(miss_{cache}*miss_{main})

(20+60+12,000,000)*(0.10*0.01)=12000.08 ns

The average time required to access a referenced word on this system is simply the sum of above 3 cases

T_{average} =18+7.92+12000.08=12026ns
