SYSTEM FOR PREFETCHING DATA INTO A CACHE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18169118 titled 'SYSTEM FOR PREFETCHING DATA INTO A CACHE
The abstract of this patent application describes a delta prefetcher that makes predictions based on both past memory accesses and predictively prefetched memory accesses. Specifically, it uses the difference or "delta" between memory addresses of previously fetched data and predictively fetched data to make predictions. The delta prefetcher utilizes two tables - the fetch table tracks memory deltas for each memory operation executed by the CPU, while the delta table predicts the next memory address to prefetch based on past prefetches.

Original Abstract Submitted
In one aspect, a delta prefetcher disclosed herein bases its predictions on both past memory accesses and predictively prefetched memory accesses. More specifically, the delta prefetcher disclosed herein bases its prediction on both the difference or “delta” between memory addresses of data previously fetched from memory and the difference or “delta” between addresses of data predictively fetched from memory. The delta prefetcher tracks the delta memory accesses by utilizing two distinctive tables. The fetch table tracks the memory deltas for each memory operation, such as a LOAD or STORE instruction, that the CPU has executed. The delta table predicts the next memory address to prefetch based on the last prefetched memory accesses.
