Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced that it joined The Linux Foundation
and Automotive Grade Linux (AGL), a collaborative 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.

IHS projects that by 2020, Linux will lead the estimated 130 million unit in-vehicle-infotainment (IVI) market with a 41.3 percent share, taking 53.7 million units. Linux adoption is growing because it provides automotive designers with an open-source platform that allows them to maximize the reuse of existing work, while making their own incremental improvements. Additionally, AGL was built on top of a well-tested and 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 IVI and advanced-driver-assistance systems (ADAS), accelerating development via open-source software and the automotive-industry-proven MOST networking technology.
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.
