TLB thrashing. Where the translation lookaside buffer (TLB) acting as a cache for the memory management unit (MMU) which translates virtual addresses to physical addresses is too small for the working set of pages. TLB thrashing can occur even if instruction cache or data cache thrashing are not occurring, … See more In computer science, thrashing occurs when a computer's virtual memory resources are overused, leading to a constant state of paging and page faults, inhibiting most application-level processing. This … See more • Page replacement algorithm – Algorithm for virtual memory implementation • Congestion collapse – Reduced quality of service due to high network traffic • Resource contention – Conflict over access to a shared resource See more Virtual memory works by treating a portion of secondary storage such as a computer hard disk as an additional layer of the cache hierarchy. … See more Thrashing is best known in the context of memory and storage, but analogous phenomena occur for other resources, including: Cache thrashing Where main memory is accessed in a pattern that leads to … See more WebA translation lookaside buffer (TLB) is a memory cache that stores the recent translations of virtual memory to physical memory.

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. bookcase with sliding doors for kids
