Abstract
Efficiently polling a DMA module to determine if the DMA copying of a packet payload to an application buffer is complete. For communication packets received from a network, a processing module may be configured to poll the DMA module at times when it is likely that the DMA copying of packet payloads is complete. Packets may be received and processed in batches. The polling of the DMA module for a packet belonging to a first batch may be deferred until the processing of a next batch. An exception may occur if a predefined amount of time elapses following the completion of the processing of the first batch before the next batch is received. In response to the predefined amount of time elapsing before the receipt of the next batch, the DMA module may be polled, i.e., prior to the next batch being processed.
