Respuesta :
For an instruction-cache miss, data-cache miss, or TLB miss, the CPU must visit main memory. The third and easiest scenario is when the desired data is already present in a cache but the data needed for virtual-to-physical translation is not.
What do you mean by Translation Lookaside Buffer (TLB) ?
The most recent translations from virtual memory to physical memory are kept in a memory cache called a translation lookaside buffer (TLB). It is employed to speed up the process of accessing a user memory location. An address-translation cache is what it is.
- It is a component of the memory-management unit on the chip (MMU). Between the CPU and the CPU cache, between the CPU cache and the main memory, or between the several layers of the multi-level cache are possible locations for a TLB.
- TLBs are commonly found in the memory-management circuitry of desktop, laptop, and server CPUs, and they are almost always present in processors that use paged or segmented virtual memory.
