a$.(3$ points$)$ Assume that the CPU is trying to retrieve a virtual address. The

address is in a page that has just been retrieved from disk when the

preceding virtual address was processed. What is the time to access this new

address?

b$.(3$ points$)$ Assume that the CPU is trying to retrieve a virtual address. The

address is in a page that has already been retrieved from disk. However, this

retrieval was a relatively long time ago and neither the TLB nor the L$1$ cache

have any relevant info for this access. What is the time to access this

address?

c$.(3$ points$)$ Given the configuration above, give the effective access time for a

lookup in the page table $($this is just for the lookup $$ you are not concerned

about the cost of a page fault$).$

d$.(3$ points$)$ Assume that all caches have been disabled $($no TLB$,$ no data

caches, etc.$).$ The CPU now receives a virtual address. In this scenario, what

is the effective access time to retrieve the value associated with this virtual

address?
