Central processing unit cache (CPU cache)

What is Central Processing Unit Cache (CPU Cache)?
Central processing unit cache (CPU cache) is a type of Cache memoryA computer processor uses data and programs much faster than host memory or random access memory (RAM). It enables the storage and provision of access to frequently used programs and data.

CPU cache is also known as processor cache.

The CPU cache is one of the most common types of cache memory. Usually the CPU cache is embedded directly on or near the processor.

When searching for data or a program, the CPU first checks the CPU cache. The CPU cache is generally of a smaller capacity than the main RAM, but because of its better internal structure and proximity to the CPU, it has faster processing capabilities; Thus it delivers the requested data faster.

There are three main types of CPU cache:

- Command cache
- data cache
- Translation lookaside buffer (TLB)
