When changing processes, the TLB of the old process is to be deleted, and a new TLB is created for the new process in a new table. This process is known as TLB shootdown. Note that the the old TLB are not stored in cache. TLB thrashing occurs when it visits pages all over the place in and out between the cache and disk memory

WebThe TLB is a specialized cache that translates logical addresses to physical addresses for a small set of active pages. Like ordinary caches, it may have hierarchical levels and may be split for instructions versus data. If a memory access is made to a page not currently in the TLB, then a TLB miss occurs.
WebA TLB hit means a PTE is present in the TLB and the processor has found it, given a virtual address. When this happens, the CPU accesses the actual location in the main memory. It consists of these steps: The CPU generates a virtual address. This is a logical address. The address is checked in the TLB and is present.
