Automotive In-Vehicle-Infotainment (IVI) systems that feature embedded SoCs running Linux for the GUI on an MPU and embedded RTOSs on MCUs for some of the more real-time/routine functions. Energy efficiency is secondary to the unnecessary cost/performance profile of building in a GPU to render relatively simple dashboard graphics.

The automotive market is the fastest-growing (and one of the largest) vertical markets for embedded MCU/MPUs, and by extension, embedded software.
