Abstract: A data message decoder for high-speed serial bus applications includes a sync pattern decoder that is operated in parallel and simultaneously with a message bit decoder. By operating the sync pattern decoder and the message bit decoder in parallel and simultaneously a true sync pattern following a valid looking sync pattern may be identified and the decoding of the bit message following the valid looking sync pattern may be aborted once the true sync pattern is detected. The data message decoder is robust and tolerant of bus anomalies that are typical when using high frequency signaling on a multipoint serial bus. The robust data message decoder is suitable for, but not limited to, applications in the aerospace industry, such as onboard network systems for advanced commercial and military aircraft.

Abstract: The present invention provides a network controller that directs communications with a variety of remote devices via a common bus. The network controller includes a transmitter for transmitting messages via the common bus, and a receiver for receiving messages from the common bus. Additionally, the network controller includes a clock for providing clock signals to both the transmitter and receiver. The transmitter and receiver are selected such that the network controller is capable of selectively operating in either synchronous or asynchronous mode. In operation, the network controller is configured in either a Manchester encoding or a Universal Asynchronous Receiver Transmitter (UART) protocol. The transmitter transmits messages comprising a command and an address of at least one remote device. In one embodiment, the transmitter simultaneously transmits messages to a plurality of remote devices in accordance with a group address comprised of a multiple bits with each bit associated with a respective group.

Abstract: Data message sync patterns for use in a network that utilizes Manchester (Bi-Phase) signal encoding with an embedded sync pattern. The sync pattern of the invention differs from conventional sync patterns for Manchester (Bi-Phase) type signal encoding, allowing greater deviation of the local oscillators in the communication network without increase in the communication network bandwidth.
