Can you help me asap?

Q3 (20 points) - Consider a demand-paging system with a paging disk that has an average access time of 5 milliseconds. Addresses are translated through a page table in main memory, with an access time of 1 microsecond per memory access. Thus, each memory reference through the page table takes two memory accesses (assuming no page faults occur). To improve this, we have added an associative memory close to the CPU that reduces access time to one memory reference for entries present in the associative memory. Assuming that 80 percent of memory accesses are resolved in the associative memory and that, 10 percent of the remaining accesses (i.e., 2 percent of the overall) result in page faults, Calculate is the effective memory access time, and explain your reasoning behind your calculation. 04 (20 points) - Consider a demand-paging system with the following measured utilization values - CPU Utilization - Paging disk utilization 20% 97.7% 5% Utilization of other I/O devices Discuss, for each of the following actions, whether it will (or is likely to) improve CPU utilization Explain and justify your answers. Installing a faster CPU Installing a disk with more capacity Increasing the degree of multiprogramming (i.e., increasing the number of - - running processes) Decreasing the degree of multiprogramming (i.e, decreasing the number of running processes) Installing more memory -

Explanation / Answer

Ans: 2nd Q

Ans Q1.

associative memory is nothing but TLB here

but as page fault is here in this case average memory access will be

Given TLB access time=0,tlb hit=0.8 and page fault rate =0.02 and page servie time=5ms.

by solving equation 1) and 2) calculate EMAT
