How to work Motherboard Cache

Particular main memory addresses are preassigned to specific line places in the cache where they will be stored in a direct-mapped cache. As a result, the tag RAM can use fewer bits since only one address tag has to be verified when you know the main memory address you want, and each tag just needs to hold the potential addresses a particular line can contain. Because only one tag address needs to be verified for a particular memory location, this results in quicker operation.

A modified direct-mapped cache is a set-associative cache. A direct-mapped cache has a single set of memory associations, which means that a particular memory address may only be mapped onto (or connected with) a single cache line location. A two-way set-associative cache contains two sets, allowing a memory location to be in either of two places. A four-way set-associative cache may store a memory address in four separate cache line places at the same time (or sets). The possibility of finding a value rises when the set associativity is increased; however, it takes a bit longer since more tag addresses must be evaluated when looking for a certain place in the cache.

In an n-way set-associative cache, each set is essentially a subcache with associations to each main memory location. The cache ultimately becomes completely associative, meaning that any memory address may be placed in any cache line location, as the number of subcaches or sets grows. An n-way set associative cache is a compromise between a completely associative and a direct-mapped cache in this situation.
