TLB Effective Access Time

]

Assume a system has a TLB hit ratio of

90 % .

When a TLB hit occurs, it takes

210

nanoseconds to access a desired instruction or data in memory. In case of a TLB miss, the access time to a desired instruction or data in memory becomes

410

nanoseconds. If we assume the TLB access time is

10

nanoseconds,

1)

what is the memory access time?

2)

Additionally, what is the effective memory access time in nanoseconds for this system?
