WebApr 5, 2024 · Translation Lookaside Buffer (i.e. TLB) is required only if Virtual Memory is used by a processor. In short, TLB speeds up the translation of virtual addresses to a physical address by storing page-table in faster memory. In fact, TLB also sits between CPU and Main memory. Webtaken by the operating system when a page fault occurs. A page fault occurs when a process addresses a page whose valid/invalid bit is set to invalid. it also can be stated that this happens when a process addresses a point in logical memory that is not currently in physical memory. 1.When a page fault occurs, the OS traps, suspending the process.
