Cache prefetching is a technique used by central processing units (CPUs) to boost execution performance by fetching instructions or data from their primary or main storage in slower memory to a faster local memory before it is actually needed. Most modern CPUs have fast and local cache memory in which prefetched data is held until it is required.
