  • Direct memory access (DMA) controller issues memory access requests whereas memory locations having addresses which are offset amounts relative to destination template address
    Patent number: 11995013
    Abstract: A direct memory access (DMA) controller comprises template storage circuitry to store at least one DMA template indicative of a DMA data access pattern. Each DMA template comprises enable indications settable to an enable state or a disable state. In response to a DMA command associated with a source address, a destination address, a source DMA template, and a destination DMA template, DMA control circuitry generates a set of DMA memory access requests to copy data from source memory system locations to destination memory system locations. The source/destination memory system locations are selected to have addresses which are offset relative to the source/destination address by offset amounts corresponding to positions of enable indications set to the enable state within the source/destination DMA template. The source/destination DMA templates allow irregular patterns of DMA accesses to be controlled in fewer DMA commands.
