摘要：
A method for arbitrating between direct memory access task requests, the method includes receiving multiple DMA task requests; the method is characterized by selecting a DMA task request out of the multiple DMA task requests in response to timing deadlines associated with the DMA tasks. A device that includes an interface, that is adapted to receive DMA task requests; the device is characterized by including an arbiter that is adapted to select a DMA task request out of the multiple DMA task requests in response to timing deadlines associated with the DMA tasks.
