please , i need the solution of this question from computer system architecture book for morris mano:
q:the access time of cache memory is 100 ns and that of main memory
1000 ns. it is estimated that 80% of the memory requests are for read
and the remaining 20% for write. the hit ratio for read access only is
0.9. a write -through procedure is used.
a- what is the average access time of the system considring only
memory read cycles?
b-what is the average access time of the system for both read asn
write requests?
c-what is the hit ratio taking into consideration the write cycles?
please, we are appreciating any response .
