A system design concept for integrating mixed criticality applications onto a single controller – and a single operating system – all while maintaining safety standards.
Car users want immersive and interactive in-vehicle experiences, especially as autonomous driving technology takes over more of our driving responsibilities. To satisfy this demand, automotive manufacturers are deploying multiple display environments in their cars, from cockpits to heads-up displays and from central infotainment screens to rear-seat entertainment. All of these displays are powered by a cutting-edge graphics processor which, thanks to the current trend of automotive compute centralisation, is typically hosted within a single cockpit controller.
Integrating hardware and software components with varying levels of criticality and safety within a single Electronic Control Unit (ECU) like a cockpit controller has become a key strategy for OEMs looking to balance advanced features, cost efficiency, and software definition. But it presents a number of system engineering challenges, one of which is how to deliver the functionality and user experience required without compromising safety standards.
Safety standards exist to prevent accidents. They are an integral component of automotive system design, ensuring that faults are detected and handled in a timely and appropriate manner. Imagination Technologies is a leading supplier of functionally safe automotive technology for cockpit, ADAS and multi-domain controllers. Our engineers were the first to develop a functionally safe GPU IP, and our recent breakthroughs have removed the overheads traditionally associated with designing processing logic that meets the relevant Automotive Safety Integrity Level (ASIL) criteria. Now, we are presenting a system design concept for integrating mixed criticality applications onto a single controller – and a single operating system – all while maintaining safety standards.
