Bit-mapped DMA transfer with dependency table configured to monitor channel between DMA and array of bits to indicate a completion of DMA transfer

A method for monitoring data transfers associated with one or more direct memory access (DMA) engines, the method comprising:

• maintaining data transfer completion (DTC) information indicative of a completion status for each of the data transfers, wherein the DTC information includes an array of DTC bits wherein each DTC bit in the array is identified by a tuple comprising an index and a subindex and wherein maintaining the DTC information includes;
• assigning a tuple to each of the data transfers;
• responsive to receiving, from a DMA engine completing a first DMA transfer associated with a first tuple, an update request indicative of the first tuple, setting a DTC bit corresponding to the first tuple to a value indicative of a completion of the first DMA transfer;
• and
• responsive to receiving, from a DMA engine executing a dependent data transfer, a monitoring request indicative of a second tuple and further indicative of a particular bit of a monitoring channel, configuring a monitoring channel between the DMA engines and the array of DTC bits, wherein a value of a DTC bit corresponding to the second tuple is indicated on the particular bit of the monitoring channel.
