Data prefetch mechanisms
WebJul 23, 2024 · I know that readahead is a form of prefetching in the Linux kernel, except I have the notion that prefetching is more about hardware (cache) pre-loading whereas … WebThis prefetching mechanism uses the underlying data of the application, and provides an 11.3% speedup using no additional processor state. By adding less than ½% space overhead to the second level cache, performance can be further increased to 12.6% across a range of "real world" applications. References H.-J. Boehm.

WebJun 1, 2000 · Rather than waiting for a cache miss to initiate a memory fetch, data prefetching anticipates such misses and issues a fetch to the memory system in advance … WebData prefetching has been proposed as a technique for hiding the access latency of data referencing patterns that defeat caching strategies. Rather than waiting for a cache miss to initiate a memory fetch, data prefetching anticipates such misses and issues a fetch to the memory system in advance of the actual memory reference.
