Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and support desired performance levels for latency and throughput while controlling memory footprint.

Localized dynamic channel time allocation

In a media access control (MAC) processor, a programmable controller is configured to execute machine readable instructions for implementing MAC functions corresponding to data received by a communication device. A tightly coupled memory is associated with the programmable controller. A system memory is coupled to the programmable controller via a system bus, and a hardware processor is coupled to the system bus and the tightly coupled memory. The hardware processor is configured to implement MAC functions on data received in a communication frame, store, in the tightly coupled memory, processed data corresponding to data in the communication frame that indicates a structure of downlink data in the communication frame, and store, in the system memory, processed data corresponding to other data in the communication frame.

As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and address the need to meet latency and throughput requirements while limiting memory footprint.

A media access control (MAC) processor includes a programmable controller and a memory coupled to the programmable controller to store machine readable instructions for implementing MAC functions corresponding to data received by a communication device. A hardware processor is coupled to the programmable controller. The hardware processor includes a processing engine configured to implement MAC functions on the data received by the communication device. The hardware processor additionally includes a context memory coupled to the processing engine to store state information of the processing engine corresponding to one or more contexts, and context switch logic coupled to the processing to determine when the processing engine should switch contexts.
