Problem 6 (13 points) The page table below is for a system with 16-bit virtual as well as physical addresses and with 4,096-byte pages. The reference bit is set to 1 when the page has been referenced. Periodically, a thread zeroes out all values of the reference bit. A dash for a page frame indicates the page is not in memory. The LRll pagg-replacement algorithm is used. The numbers are given in decimal Page Frame eferepceit 14 10 13 15...

For part A: convert the virtual address into page numbers and
offset, and then into hexadecimal numbers. Redraw the page table
showing which pages were referenced and in any needed to be loaded
into memory and what frame was selected. Assume frames 6,7,11,and
12 are available.

17. A computer system implements a paged virtual memory system. Assume a 16-bit virtual address space and a 24-bit physical address space. Assume that the first 6 bits of a virtual address index the page table and the rest of the bits are the page offset. A process has the following indexed page table. Index Page Table Entry (PTE) 0x3800 0x3600 0x3200 0x1000 2 3 Each page table entry qives a hexadecimal page frame addresses. Translate the following two hexadecimal...

Consider the following virtual page reference sequence: page 1, 2, 3, 4, 2, 1, 5, 6, 2, 1, 2, 3. This indicates that these particular pages need to be accessed by the computer in the order shown. Consider each of the following 4 algorithm-frame combinations: LRU with 3 frames FIFO with 3 frames LRU with 4 frames FIFO with 4 frames . For each of the 4 combinations, below, move from left to right as the virtual page numbers are...
Suppose you have a byte-addressable virtual address memory system with 8 virtual pages of 64 bytes each
Suppose you have a byte-addressable virtual address memory system with 8 virtual pages of 64 bytes each, and 4-page frames. Assuming the following page table, answer the questions below: Page #Frame #Valid Bit0111312-03014215-06-07-0a) How many bits are in a virtual address? b) How many bits are in a physical address? c) What physical address corresponds to the following virtual addresses (if the address causes a page fault, simply indicate this is the case)? 1) Ox00 2) 0x44 3) OxC2 4) 0x80
