A method for hardware management of DMA transfer commands includes accessing, by a first DMA engine, a DMA transfer command and determining a first portion of a data transfer requested by the DMA transfer command. Transfer of a first portion of the data transfer by the first DMA engine is initiated based at least in part on the DMA transfer command. Similarly, a second portion of the data transfer by a second DMA engine is initiated based at least in part on the DMA transfer command. After transferring the first portion and the second portion of the data transfer, an indication is generated that signals completion of the data transfer requested by the DMA transfer command.
