TLBcachen
TLBcachen is a component within some computer system architectures, specifically related to memory management. It functions as a cache for the Translation Lookaside Buffer (TLB). The TLB itself is a cache used by the virtual memory system of most modern operating systems to speed up virtual-to-physical address translation. When a program needs to access a memory location, the system first checks the TLB for a cached translation. If the translation is found, it is used directly, avoiding a slower lookup in the page table.
A TLBcachen extends this concept by providing another layer of caching for TLB entries. This means that
