Q) what is the maximum acceptable page-fault rate for an effective memory access time (the time for an application program to do one memory reference) of no more than 1400 NANOSECONDS? show all step of the computation.

3. (15 points total) One of your friends has a little extra money to spare and has decided to upgrade their HAL Junior HALZ4u computer. The HAL Junior has a simple paged virtual memory system (with no segments). First you measure the system to find out why it is running so slow. You discover the following values: Measurement Value 0.1 0.0002 0 1 microsecond 10 milliseconds 10000 microseconds 0.5 Pt probability of a TLB miss Po = probability of a page fault when a TLB miss occurs Tt- time to access TLE Tm- time to access memory Td-time to transfer a page to/from disk Pd -probability page is dirty when replaced The TLB is refilled automatically by the hardware on a miss (the TLB is only accessed once per reference). The page tables are kept in physical memory, so looking up a page table entry incurs one memory access. Assume that the costs of the page replacement algorithm and updates to the page table are included in the Td measurement
