First it was drive-by-wire which cut the mechanical linkage between the gas pedal and the engine, now all the rest of the subsystems on a car are getting networked, thus eliminating the need for dedicated wires, potentially saving up to 150 pounds by nixing the need for four miles of copper wire. By using Freescale's smarter Qorivva processors--announced today at Semicon China 2013--connected by Ethernet to satellite 12-MagniV microcontrollers, almost every electronic subsystem in a vehicle can be networked: R. Colin Johnson @NextGenLog
Freecale's latest Qorivva MPC5748G provides support for Ethernet with Audio Video Bridging, FlexRay, Media Local Bus, USB, CAN FD and up to 18 LIN controllers, allowing its MagniV devices to reduce printed circuit board sizes by as much as 30 percent.Further Reading
