Advanced Virtualization in Automotive Operating System: Technology Overview and Scheme Design

Intelligent connected vehicles (ICV) are a key area of competition that is a new driving force for global technological change and technological innovation in vehicles, and the development of its operating system has become an increasingly important priority. As the transformation of vehicles electronic and electrical architecture accelerates, the cross-domain integration of vehicles operating systems has become a general trend. As the main technology for cross-domain integration, virtualization technology is bound to become a battleground for various vehicle manufacturers. This paper aims to take an in-depth look at virtualization of automotive operating systems. Specifically, the overall architecture of operating system virtualization is described first, and then the key functional modules are analyzed in detail, including CPU, memory, interrupts, I/O devices and GPU virtualization technology. Then, a API forwarding-based UV-GPU virtualization scheme is especially designed whose implement details and development prospect in ICV are deeply discussed.
