| 摘要 | A method includes assigning a plurality of pads of an integrated circuit (IC) to a direct memory access (DMA) channel of the IC; and storing DMA requests associated with the pads in a queue such that at a given time, the queue stores data indicative of DMA requests that are associated with more than one pad. | ||

| 主权项 | 1. A method comprising: programming a direct memory access (DMA) interface of an integrated circuit (IC) to assign a plurality of pads of the IC to a direct memory access (DMA) channel of the IC; storing data indicative of DMA requests associated with the pads in a queue of the DMA interface such that at a given time the queue stores data indicative of DMA requests associated with more than one pad of the plurality of pads; associating a pad controller of the DMA interface with a given pad of the plurality of pads; and using the pad controller to communicate data between the DMA interface and a memory of the IC when a DMA channel is assigned to the given pad. | ||
