  • Patent number: 9054825
    Abstract: Embodiments of the present invention provide a method that includes receiving, by a traffic arbiter, a predetermined time-slot allocation of one or more uplink time slots and/or one or more downlink time slots for a first wireless media access control (MAC) configured to operate within a first wireless transmission system. The method also includes determining, by the traffic arbiter, whether to grant a second wireless MAC, configured to operate within a second wireless transmission system, permission to transmit or receive based at least in part on the predetermined time-slot allocation.
    Type: Grant

  • Patent number: 8897293
    Abstract: 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.

  • Patent number: 8175015
    Abstract: 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.
