Consider a cache with a line size of 64 bytes. Assume that on average 30% of the lines
in the cache are dirty. A word consists of 8 bytes.
a. Assume there is a 3% miss rate (0.97 hit ratio). Compute the amount of main
memory traffic, in terms of bytes per instruction for both write-through and writeback
policies. Memory is read into cache one line at a time. However, for write
back, a single word can be written from cache to main memory.
Here nothing is given on how many instructions,no of reads or write are more etc.I am trying this by assuming 100 instructions,but how to divide this in no of read and write instructions and then calculate read hits,read miss,write throughs. I tried to search in solution manual but I am not understanding the solution given.Please help.
