The Role of CPU Cache in Enhancing System Performance
The Central Processing Unit (CPU) is a critical component of any computer, and its performance can be greatly influenced by the presence and size of the CPU cache. In this article, we'll explore what CPU cache is, how it works, and its significance in enhancing system performance.
Understanding CPU Cache
CPU cache is a small, high-speed memory unit located within the CPU itself. Its primary purpose is to store frequently accessed data and instructions that the CPU can quickly retrieve, rather than fetching them from the slower main memory (RAM). CPU cache is essential because accessing data from main memory is comparatively slower due to the physical and electrical limitations of RAM.
Types of CPU Cache
There are typically three levels of CPU cache:
Level 1 (L1) Cache: This ...
