WebEmulating a Recently Used Bit (Hardware Loaded TLB) • Some processor architectures do not keep a recently used bit per page –Extra bookkeeping and complexity • Kernel can emulate a recently used bit: –Set all recently unused pages as invalid –On first read/write, trap into kernel –Kernel sets recently used bit –Marks page as read or read/write

WebThe simplest page-replacement algorithm is a FIFO algorithm. The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires little bookkeeping on the part of the operating system.

WebThis is the strange behavior shown by FIFO algorithm in some of the cases. This is an Anomaly called as Belady'sAnomaly. Let's examine such example : The reference String is given as 0 1 5 3 0 1 4 0 1 5 3 4. Let's analyze the behavior of FIFO algorithm in two cases. Case 1: Number of frames = 3 Number of Page Faults = 9 Case 2: Number of frames = 4 WebTranslation lookaside buffer (TLB) caches virtual to physical address translation information and is used in systems ranging from embedded devices to high-end servers.

WebUse the FIFO replacement policy to choose the frame to replace if there are no free frames. Update the TLB and page table with the new mapping. Go to step 2 to access the memory using the new frame number. Using these steps, here is the resulting TLB and page table after processing the given address requests: WebTwo options: 1) hardware sets use bit in TLB; when TLB entry is replaced, sofware copies use bit back to page table 2) Sofware manages TLB entries as FIFO list; everything not in TLB is second chance list, managed as strict LRU 5.4 Core map page tables map virtual page # ¯physical page # Do we need the reverse?
