Abstract: A vehicular autonomous driving system includes a fault prediction unit, including a processor and memory, configured to predict a potential future fault condition by: monitoring performance data associated with the plurality of autonomous driving components; comparing the performance data associated with the plurality of autonomous driving components to a plurality of performance thresholds; and determining the potential future fault condition for one of the plurality of autonomous driving components, when the performance data associated with the one of the plurality of autonomous driving components compares unfavorably to a corresponding one of the plurality of performance thresholds.

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: An example SoC includes a plurality of processing systems supporting respective Quality of Service (QoS) rules, channel circuitry that is configured to service communications for the plurality of processing systems and that includes a QoS manager. The QoS manager determines that a first processing system of the plurality of processing systems that operates according to first QoS rules desires to send a communication with a first QoS selection of the first QoS rules to a second processing system that operates according to second QoS rules, determines available communication receipt resources of the second processing system of the plurality of processing systems, the second processing system supporting second QoS rules, determines a communication resources allocation for the second processing system based upon the first QoS rules, the second QoS rules, and the first QoS selection, and directs the second processing system to operate according to the communication resource allocation.

Abstract: An autonomous driving controller includes a plurality of parallel processors operating on common input data. Each of the plurality of parallel processors includes a general processor, a security processor subsystem (SCS), and a safety subsystem (SMS). The general processors, the SCSs, and the SMSs of the plurality of parallel processors are configured to first, boot the plurality of SCSs from ROM second, boot the plurality of SMSs of the plurality of parallel processors from RAM or ROM, and, third, boot the plurality of general processors of the plurality of parallel processors from RAM. Between booting of the SCSs and the SMSs, at least one of the plurality of SCSs may load SMS boot code into the RAM that is dedicated to the plurality of SMSs.
