Abstract

An apparatus includes an integrated circuit that includes a processing core and a direct memory access (DMA) engine. The DMA engine is adapted to process descriptors to control DMA communications. The descriptors contain data indicating communication endpoints that are associated with the DMA communications. The DMA engine is adapted to use other data contained in at least one of the descriptors to control branching of descriptor execution among multiple execution paths.
