Abstract
A signature is generated to indicate a direct memory access (DMA) operation involving a transfer, by a DMA engine, of data between a host memory circuit and an endpoint memory circuit of an endpoint processor circuit. First descriptors of the DMA engine are defined relative to the endpoint memory circuit or host memory circuit. A signature is received that indicates that second descriptors have been configured by the endpoint processor circuit. In response to receiving the endpoint signature, the DMA engine is enabled to begin the DMA operation.
