Consider a processor is running a program $30\%$ of the instructions of which require a

memory read or write operation if the cache hit ratio is $0\mathrm{.}95$ for instruction and $0\mathrm{.}9$ for data.

When a cache hit occurs for instruction or data, only one clock cycle needed, while cache

miss penalty is $17$ clocks to read$/$ write on the memory. Calculate the time saved by using

cache, given the total number of instructions executed are $1$ million $($Assume $10$ clock cycle

need for without cache$).$
