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. WebPrefetching strategies are diverse and no single strategy has yet been proposed which provides optimal performance. The following survey examines several alternative …

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.

The processor assumes that this access is part of a streaming algorithm and automatically fetches the next line.
