Microchip Technology recently announced that it joined The Linux Foundation and Automotive Grade Linux (AGL), which is an open-source project developing a common, Linux-based software stack for the connected car. Additionally, Microchip has begun enabling designers to use the Linux operating system with its portfolio of MOST network interface controllers.
AGL was built on top of a stable Linux stack that is already being used in embedded and mobile devices. The combination of MOST technology and Linux provides a solution for the increasing complexity of in-vehicle-infotainment (IVI) and advanced-driver-assistance systems (ADAS).
The MOST network technology is a time-division-multiplexing (TDM) network that transports different data types on separate channels at low latency and high quality-of-service. Microchip’s MOST network interface controllers offer separate hardware interfaces for different data types. In addition to the straight streaming of audio or video data via dedicated hardware interfaces, Microchip’s new Linux driver enables easy and harmonized access to all data types. Besides IP-based communication over the standard Linux Networking Stack, all MOST network data types are accessible via the regular device nodes of the Linux Virtual File System (VFS). Additionally, high-quality and multi-channel synchronous audio data can be seamlessly delivered by the Advanced Linux Sound System Architecture (ALSA) subsystem.
Support is currently available for beta customers. The full version is expected for broad release in October.
