From the embedded point of view, a car is a LAN with a large number of CPUs ranging from internally complex SoCs running Linux to single-task MCUs running an RTOS. These devices engage in what is often time-critical communication using a variety of legacy protocols, although IP and possibly TCP and UDP are making inroads. Regionally differentiated requirements for emergency traffic messages sent over new vehicle-vehicle and vehicle-infrastructure channels add complexity. The diversity of internal automotive networks coupled with needs for security, time-critical IPC, low cost and maximum electromechanical robustness make for difficult design decisions. The U.S. specification of early backup-camera images with composited markers complicates implementation. The GENIVI consortium and the new Automotive Grade Linux distro represent approaches to a solution.
member, technical staff, Mentor Embedded Software Division
Alison recently joined Mentor Graphics Embedded Software Division. Her IVI technical work has focused on the never-ending problem of getting the audio and graphics stacks to work properly with Linux. She comes into contact with Bay Area IVI innovators as the organizer of the 550+-member Silicon Automotive Open Source Group. In the last few years Alison has shown many IVI demos, including several at Linux Foundation events. She started on IVI with... Read More →
