Implementing MOSTCO's Roadmap
Despite the media hype about Ethernet in the car, the MOST technology is still far more established in the infotainment domain than any other networking technology. The current roadmap, introduced at this year’s MOST Forum has been enhanced; additional waypoints and goals have been added to the roadmap. This article addresses the most significant aspects of these goals, the status and the outlook from Microchip’s perspective.
License Agreement issued by the CI Plus LLP ( www.ci-plus.com). CI+ now allows a MOST network to transport CI+ protected content using Digital Transmission Content Protection (DTCP). This agreement with the CI Plus LLP enables the transmission of the latest digital video broadcasts to be transported between vehicle components over a MOST network. MOST150 enables direct isochronous transport of, for example, MPEG video streams, without bit stuffing or transcoding. In addition to the approved content protection schemes for Digital Transmission Content Protection (DTCP) and HDCP, MOST allows the transportation of CI+ protected content. Microchip’s free DTCP software stack supports cost-efficient, content-protected communication on MOST.

Another example is Microchip’s work with the Linux Foundation. When Microchip joined the Linux Foundation in December 2014, Microchip became part of the Technical Advisory Board mentoring program and thereby, gained the opportunity to have Microchip’s MOST Linux Driver code reviewed by Greg Kroah-Hartman, as a mentor. This pushed the driver upstream to the mainline kernel. This one-on-one mentoring process helped put Microchip’s code on the fast track toward acceptance. Microchip is committed to Automotive Grade Linux (AGL) and is prepared to address the needs in terms of the quality of its contributed code and in its role as the automotive subsystem maintainer. Linux Mainline Kernel starting with Version 4.3 includes a Microchip MOST Linux driver. The driver enables access to all MOST data types and supports the USB, MediaLB and I2C interfaces of MOST network interface controllers. The driver supports standard Linux interfaces like ALSA (Audio), V4L2 (Video) and IP-based communication over the standard Linux Networking Stack. During the 2016 Consumer Electronics Show in Las Vegas, the Automotive Grade Linux project showed a demonstration of the new Unified Code Base distribution. This demonstration was the collaboration of many companies including Microchip’s Automotive Divisions, Pioneer, Panasonic, Renesas, and K2L. All these companies contributed code, helped integrate the software, and built the hardware.
