Consider a paging system that uses a page table residing in main memory and a TLB for address translation. Each main memory access takes 150 ns and TLB lookup takes 30ns. Assume that the TLB hit ratio is 90%, evaluate the effective memory access time from the above information.

Consider a paging system that uses a page table residing in main memory and a TLB for address translation. Each main memory access takes 100 ns and TLB lookup takes 20ns. Each page transfer to/from the disk takes 5000 ns. Assume that the TLB hit ratio is 90%, page fault rate is 15%. Assume that for 25% of the total page faults, a page has to written back to disc before the required page is read in from disk. Evaluate the effective memory access time from the above information

Consider an associative translation look aside buffer (TLB) with access time six (6) milliseconds. 85% of all page-table references are found in the TLB and other 15% is found in the page table. Page table access time is 15 milliseconds. Evaluate the effective memory reference time from the above information

Please describe Clearly so that everything is understanble
