prefetcher
A prefetcher is a component in computer architecture designed to improve system performance by predicting and fetching data or instructions from memory before they are actually needed. This proactive approach helps to reduce latency and keep the processor busy, thereby enhancing overall efficiency.
Prefetchers operate on the principle of locality, which includes temporal locality (recently accessed data is likely
There are several types of prefetchers, including stream prefetchers, stride prefetchers, and tagged prefetchers. Stream prefetchers
The effectiveness of a prefetcher depends on various factors, including the accuracy of its predictions, the
Modern processors often incorporate sophisticated prefetching mechanisms to optimize performance. These mechanisms are typically implemented at
