SYSTEM FOR PREFETCHING DATA INTO A CACHE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240184700 titled 'SYSTEM FOR PREFETCHING DATA INTO A CACHE
Simplified Explanation
The abstract describes a delta prefetcher that predicts memory accesses based on the difference between previously fetched data and predictively fetched data.
- The delta prefetcher uses memory deltas to make predictions.
- It tracks memory deltas using fetch and delta tables.
- The fetch table tracks memory deltas for each memory operation executed by the CPU.
- The delta table predicts the next memory address to prefetch based on past prefetches.
Potential Applications
This technology could be applied in:
- Computer processors
- Data centers
- Cloud computing environments
Problems Solved
The delta prefetcher helps in:
- Reducing memory access latency

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.
