Abstract: Apparatus includes a plurality of ports and arbitration circuitry. The plurality of ports is configured to connect a memory to a respective plurality of processing units that are configured to access the memory. The arbitration circuitry is configured to grant the processing units access to the memory via the ports in accordance with an arbitration scheme including multiple, alternating priority periods, such that in each priority period a respective processing unit is assigned an absolute priority over others of the processing units and the others of the processing units are assigned predefined relative priorities over one another.

Abstract: An apparatus includes Radio Frequency (RF) circuitry, multiple message sources and strobe multiplexing logic. The RF circuitry is configured to synchronize communication of RF signals based on reception of strobe messages. The multiple message sources are each configured to generate respective ones of the strobe messages for synchronizing the RF circuitry. The strobe multiplexing logic is configured to multiplex the strobe messages originating from the multiple message sources, and to send the multiplexed strobe messages over a single digital interface to the RF circuitry.
