But i will explain a little more about tag bits. Here the size of a cashe line( which is always same as size of a main memmory block) is 8 bytes. which is 2 3 bytes. So you need 3 bits to represent a byte within a cashe line. WebIn a direct-mapped cache, each memory address is associated with exactly one location within the cache. This is inflexible but easy to implement in hardware. The block location in the cache is determined by bits in the address.

Set-associative cache is a trade-off between direct-mapped cache and fully associative cache. A set-associative cache can be imagined as a n × m matrix. The cache is divided into ‘n’ sets and each set contains ‘m’ cache lines. A memory block is first mapped onto a set and then placed into any cache line of the set.
