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.

Just looking briefly, both Qualcomm [1] and NVIDIA [2] automotive systems have on-board GPUs.

- roymurdock 10y agoCheck out Freescale and Renesas solutions. They are major automotive SoC players. The Renesas R-Car platform does integrate a dual-core Power-VR GPU: https://cache.freescale.com/files/32bit/doc/fact_sheet/IMX6SRSFS.pdf https://cache.freescale.com/files/32bit/doc/fact_sheet/IMX6S... https://www.renesas.com/en-us/solutions/automotive/products/rcar-h1.html https://www.renesas.com/en-us/solutions/automotive/products/...
- icefox 10y agoAnd the price difference between a device that didn't have gpu compared to those that don't will just shrink over time so any margin you might get yesterday will not be what you can get in the future.
- nullcipher 10y agoSame here. It would be very poor long term investment to put a chip into a car without a GPU. But, I think the Qt changes are for IoT and not for cars.
