Abstract:
A processing device, operatively coupled with a plurality of memory devices, is configured to receive a DMA command for a plurality of data sectors to be moved from a source memory region to a destination memory region, the destination memory region comprises a plurality of noncontiguous memory addresses and the DMA command comprises a destination value referencing the plurality of noncontiguous memory addresses. The processing device further retrieves the plurality of noncontiguous memory addresses from a location identified by the destination value. The processing device then reads the plurality of data sectors from the source memory region. The processing device also performs, for each respective data sector of the plurality of data sectors associated with the DMA command, a write operation to write the respective data sector into a corresponding respective noncontiguous memory address from the plurality of noncontiguous memory addresses of the destination memory region.
