The minimum number of page frames that must be allocated to a running process in a virtual memory environment is determined by
The instruction set architecture
The instruction set architecture determines how many separate instruction and operand pages may need to be resident to complete an instruction. This imposes a minimum frame allocation for forward progress; the total physical memory and number of processes affect allocation policy rather than that architectural requirement.
Important Questions from Non Contiguous
If a memory partition of size 80k is allocated to a process of size 60k then the 20k of the partition is wasted and cannot be allocated to any process. It is called _______.
If main memory access time is 400 μs, TLB access time is 50 μs, considering TLB hit as 90%, what will be the overall access time?
Which of the following is NOT a base of product related segmentation?
The purpose of a page table in a paging system is to:
Consider a single-level page table system. with the page table stored in the memory. If the hit rate to TLB is 80%, and it takes 15 nanoseconds to search the TLB. and 150 nanoseconds to access the main memory, then what is the effective memory access time, in nanoseconds ?
