Abstract: An autonomous driving controller includes a plurality of parallel processors operating on common input data received from the plurality of autonomous driving sensors. Each of the plurality of parallel processors includes communication circuitry, a general processor, a security processor subsystem (SCS), and a safety subsystem (SMS). The communication circuitry supports communications between the plurality of parallel processors, including inter-processor communications between the general processors of the plurality of parallel processors, communications between the SCSs of the plurality of parallel processors using SCS cryptography, and communications between the SMSs of the plurality of parallel processors using SMS cryptography, the SMS cryptography differing from the SCS cryptography. The SCS and/or the SMS may each include dedicated hardware and/or memory to support the communications.

Abstract: A system and method for low-cost, fault tolerant, EMI robust data communications, particularly for an EV environment.

Abstract: A data communications system having a plurality of communication devices including a host having a first receiver and a second receiver; and one or more clients, each client including a transmitter coupled between a signal node and a transmitter node, the transmitter selectively transmitting a multistate signal from the signal node to the transmitter node; and a single conductor daisy-chain loop redundantly communicating each multistate signal from each the transmitter to both receivers, the single conductor daisy-chain loop electrically communicating each transmitter node to the receivers. A data communications method including a) transmitting selectively a multistate signal from each of one or more clients; b) communicating electrically each multistate signal to a first location on a host using a single conductor coupled to each the client; and c) communicating electrically each multistate signal to a second location on the host using the single conductor.
