All major OEMs and software suppliers of the automotive industry are committed to advanced driver assistance systems (ADAS). A close look, though, raises questions on the demands ADAS applications place on compilers and toolsets. There are differences between traditional automotive applications and ADAS, and current compliers need some adaptations to better address ADAS needs.
ADAS applications as a challenge
To better support the task of driving autonomously, vehicles need to be much more aware of their surroundings. Several new sensors (Radar, Lidar, cameras, etc.) can be used to detect road markings, other vehicles, obstacles, and other relevant environmental data with high resolution (Fig. 1). In the past, it was common practice for automotive systems to process only individual measurements from specific actuators (steering angle, pedal positions, various engine sensors, etc.) in real time.
