In computing, “cache” is a vital component that enhances processor speed and efficiency by storing frequently used data and program instructions. It leverages the principles of temporal and spatial locality to optimize data access. Caching offers benefits such as speed, reduced latency, and improved efficiency but comes with considerations like size, complexity, and cost.
Read More What is CACHE?The L1, L2, and L3 caches in modern computing architectures bridge the speed gap between the CPU and RAM. L1 is integrated into the processor core for minimal latency, L2 is close to the CPU, and L3 serves multiple cores. They store instructions and data for immediate processing, with varying sizes and access times. Cache management includes algorithms for evicting entries and handling writes, while cache coherency ensures consistent memory across cores. The cache can handle write operations in different ways.
