Abstract
Method and apparatus for controlling direct access to memory circuitry by a device is described. In one example, a streaming interface is configured to transmit and receive a communication sequence to and from the device. Control logic is configured to implement a plurality of direct memory access (DMA) engines. The DMA engines are configured to read and write data to and from the memory circuitry. A set of registers is configured to store control data for the plurality of DMA engines.
