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

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