Question
A computer with cache access time of 100 ns and hit ratio of 0·9 produces an average access time o
Solution
It seems like your question got cut off. However, I can start explaining with the information given.
The average access time of a cache memory system is calculated using the formula:
Average Access Time = Hit Time + Miss Rate * Miss Penalty
Where:
- Hit Time is the time to deliver a line in the cache to the processor and it includes time to determine whether the line is in the cache.
- Miss Rate is the fraction of cache access that results in a miss and it's equal to (1 - Hit Ratio).
- Miss Penalty is the additional time required because of a miss.
Given:
- Cache Access Time (Hit Time) = 100 ns
- Hit Ratio = 0.9, hence Miss Rate = 1 - 0.9 = 0.1
We need the Miss Penalty to calculate the Average Access Time. If you provide the Miss Penalty, I can complete the calculation.

A small computer has a direct-mapped data cache of size 1 kilo Bytes. lts block size is 32 bytes, hit time is 2 processor clock cycles, and, the miss penalty is 20 processor clock cyclesWhile running a loop, in each iteration data (of size 1 byte) is accessed from memory addresses 6, 522, 768, 1028. If the loop iterates 10 times, compute the average data access time for the loop.
What is the cache hit ratio. if memory access takes 20 ns with cache and 110 ns without it (cache uses a 10 ns memory)?
If the same 1 kilo Byte cache had been organized as a two-way set associative cache (other specifications remaining the same), then what would have been the average data access time for the loop?
