What does the cache controller do?

The cache controller is hardware that copies code or data from main memory to cache memory automatically. Thus, the same application software can run unaltered on systems with and without a cache. The cache controller intercepts read and write memory requests before passing them on to the memory controller.

What is cache and how does it work?

A cache is a reserved storage location that collects temporary data to help websites, browsers, and apps load faster. Whether it’s a computer, laptop or phone, web browser or app, you’ll find some variety of a cache. A cache makes it easy to quickly retrieve data, which in turn helps devices run faster.

How does cache work in the CPU?

How does cache memory work? Cache memory temporarily stores information, data and programs that are commonly used by the CPU. When data is required, the CPU will automatically turn to cache memory in search of faster data access. This is because server RAM is slower and is further away from the CPU.

What is a cache set?

— The cache is divided into groups of blocks, called sets. — Each memory address maps to exactly one set in the cache, but data may be placed in any block within that set. Here are several possible organizations of an eight-block cache.

Is the cache part of the CPU?

Cache is a small amount of memory which is a part of the CPU – closer to the CPU than RAM . It is used to temporarily hold instructions and data that the CPU is likely to reuse.
