Abstract
A system includes a direct memory access (DMA) engine to move data on a real time basis and a communication front-end to transmit and receive the data. In another embodiment, the system may also include a medium access control (MAC) to control transmission and reception of the data and that may be partitioned or divided according to response times to carry out selected functions.
Claims28
A system, comprising:
- a communication front-end to transmit and receive data;
- and
- a direct memory access (DMA) engine adapted to move the data to and from the communication front-end in response to flow-control signals.
A system, comprising:
- a medium access control (MAC) to control transmission and reception of data;
- and
- a direct memory access engine to move the data within the system for transmission and reception.
A method, comprising:
- signaling a DMA engine data is available for transmission;
- generating a flow-control signal;
- moving data to a communication front-end in response to the flow-control signal;
- and
- transmitting the data.
2 more elements
A method, comprising:
- providing a DMA engine to transmit and receive data on a real-time basis;
- and
- coupling the DMA engine to a processor running a non-real time operating system.
