Implementation of Optimized AUTOSAR Systems for RISC-V with ARA

Within the AHA project, we focus on optimizing embedded systems by specialization of the OS itself. Using the Automatic Real-time Analyzer (ARA), we perform static analysis to enable extensive tailoring of real-time operating systems to the application. The operating system is generated specifically for a single application to provide exactly the required functionality. As a result, we improve non-functional system properties like delay or memory footprint, which can reduce hardware costs and energy consumption.

In this thesis, the AUTOSAR system generation in ARA shall be extended to another target architecture: RISC-V. As a base, the source code of dOSEK [1] can be reused. Unlike in dOSEK/OSEK-V, the system shall support multicore platforms, hence concepts like atomics and spinlocks must be implemented. To evaluate the implemented system, it can be tested against existing applications and compared to the ARM implementation.
