Consider a virtual memory system with the following properties: 36 bit virtual byte address, 8 KB pages size, and 32 bit physical byte address. Please explain how you determined your answer. a. What is the size of main memory for this system if all addressable frames are used? b. What is the total size of the page table for each process on this processor, assuming that the valid, protection, dirty, and use bits take a total of 4 bits and...

As described in 5.7, virtual memory uses a page table to track the mapping of virtual addresses to the physical addresses. This exercise shows how this table must be updated as addresses are accessed. The following data constitutes a stream of virtual addresses as seen on a system. Assume 4 KiB pages, a 4-entry fully associative TLB, and true LRU replacement. If pages must be brought in from disk, increment the next largest page number. 4669, 2227, 13916, 34587, 48870,...

Consider the following system: Byte addressable 16-bit addresses 256B pages Single level Page Table System The system utilizes a fully-associative TLB with 4 entries and an LRU replacement policy. Given the access pattern and timings below, complete the following table. Assume the TLB begins initially empty and the cache is physically addressed NOTE: Access times are not inclusive and components are accessed sequentially. Time to update the TLB is negligible, everything else that needs to be updated will require a...
