Why tlb fully associative

We are talking about a few dozen entries at most. Even L1i and L1d caches are bigger and require a combined approach: a cache is divided into sets, and each set consists of "ways". Sets are directly mapped, and within itself are fully associative. N-way set associative cache pretty much solves the problem of temporal locality and not that complex to be used in practice.

In addition to other stuff it contains 3 lectures about memory hierarchy and cache implementations. The cache reads from the 16 byte division, so for the first read it reads the first 16 bytes in from 0x1A which covers the range sought.

The conventional die-stacked DRAM cache has both a TLB and a cache tag array, which are responsible for virtual-to-physical and physical-to-cache address translation, respectively.

We propose to align the granularity of caching with OS page size and take a unified approach to address translation and cache tag management. To this end, we introduce cache-map TLB cTLB , which stores virtual-to-cache, instead of virtual-to-physical, address mappings. Email Required, but never shown.
