Since the first implementation of the Media Oriented Systems Transport (MOST) network, luxury automaker Audi has used the system to interconnect its infotainment systems. This article describes Audi's evaluation setup and process for the current MOST version, MOST150.
Using twin evaluation platforms, Audi engineers tested all of the elements affected by the migration from MOST25 to MOST150. The availability of components was confirmed and the expectations regarding data rates, stability and functions were fulfilled. Through these verification projects, Audi confirmed that MOST150 is ready for series production.
Following this knowledge, Audi forwarded MOST150 into series production development to be used as the network technology for the MIB (modular infotainment construction set (in German)). Audi and the MOST Cooperation have worked closely together in specifying communication for ring break diagnosis (RBD). Through this standardization, Audi is expecting a further enhancement in quality.

Its a great initiative by Audi, the other manufactures as well will be waiting to adopt MOST as an automotive networking protocol. This will really improve the quality of infotainment systems inside the cars.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
