"Car OS" links Linux with telematics systems
penSynergy is readying a Linux-based "car operating system" and an Intel Atom-based evaluation board for automobile infotainment systems. The COQOS platform aims to let Linux-based infotainment applications and AUTOSAR-compliant telematics modules share the same system-on-chip processor, which is virtualized by a "micro operating system" (μOS) layer.
Interestingly, the technology is said to enable both Linux and AUTOSAR apps to share a common audio and OpenGL graphic layer, enabling AUTOSAR applications to output to multimedia displays and audio for the first time, says the company. Additional touted benefits of the approach include reducing the count of ECUs (engine control units), minimizing development costs, and even increasing fuel efficiency, by reducing the weight associated with multiple, separate vehicular computer networks.
COQOS integrates a real-time micro operating system, μOS, to partition a single SoC into multiple virtual machines (VMs). The arrangement is claimed capable of partitioning a Linux-based infotainment platform from AUTOSAR operations, which is required for safety reasons.
