PROVIDING MEMORY REGION PREFETCHING IN PROCESSOR-BASED DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240176742 titled 'PROVIDING MEMORY REGION PREFETCHING IN PROCESSOR-BASED DEVICES
Simplified Explanation
The abstract describes a patent application for memory region prefetching in processor-based devices. The system includes a region prefetcher circuit with access bitmaps for memory regions, detecting memory access requests, setting bits to indicate requests, and prefetching memory blocks based on trigger events.
- Region prefetching in processor-based devices:
* Involves a region prefetcher circuit with access bitmaps for memory regions. * Detects memory access requests and sets corresponding bits in the access bitmaps. * Prefetches memory blocks based on trigger events and unset bits in the access bitmaps.

Original Abstract Submitted
providing memory region prefetching in processor-based devices is disclosed. in some aspects, a processor-based device comprises a region prefetcher circuit that comprises a plurality of access bitmaps corresponding to a plurality of contiguous memory regions of a system memory device. each access bitmap comprises a plurality of bits corresponding to a plurality of memory blocks of a contiguous memory region. the region prefetcher circuit detects a memory access request to a memory block of a contiguous memory region, identifies an access bitmap corresponding to the contiguous memory region, and identifies a bit corresponding to the memory block. the region prefetcher circuit sets the bit to indicate the memory access request to the memory block. the region prefetcher circuit subsequently detects a prefetch trigger event, and, in response, identifies one or more unset bits of the access bitmap, and prefetches one or more memory blocks corresponding to the unset bits.
