Patent ID: 11580060

Abstract:
A system includes a real-time partitioning separation kernel installed on a multi-core processor. Guest operating systems are hosted with in hardware virtualized machines in the cores. Another hardware virtualized machine performs a real-time USB-CAN interface communicatively coupled to distributed electronic control units which acquire data and command actuators. A plurality of hardware virtualized machines support processes of various criticality. A secure shared memory serves as the communication means between processes performing different levels of functionality at suitable latency ranges. a policy to distinguish, allocate, and distribute clock, memory, and input/output resources to meet focused latency ranges to the Observation, Decision, and Execution processes. Remaining resources have diffuse latency ranges made available to the Observation, Decision, and Execution processes in an as available but guarded minimum and maximum buffet. A latency policy ensures that each process receives its minimum tranche before queueing for up to the maximum at the resource buffet.
