AHA: Automated Hardware Abstraction in Operating-System Engineering (DFG: LO 1719/4-1)

Goal of AHA is to improve nonfunctional properties of system software by a very deep, but fully automated specialization of the application-hardware bridge represented by the operating system. We investigate, how alternative implementations that are mapped more directly to hardware features, can be generated from a concrete application and their actual interactions with the operating system.

Development and Analysis of an AUTOSAR Real-Time Operating System on a Multicore RISC-V Hardware Platform

In previous work, an AUTOSAR-compatible real-time operating system was developed for RISC-V in QEMU. In this thesis, it shall be deployed on real RISC-V hardware like the BeagleV®-Fire so timing measurements for RTOS-specific optimizations can be executed.

Interaction-Level Specialization of RISC-V Soft Cores for Zephyr RTOS with ARA

The specialization of Real-Time operating systems can be extended to the hardware. Using a RISC-V Soft Core, tailored hardware for the Zephyr RTOS shall be implemented.

RTOS of the Day: Performance Comparison and Analysis of Open Source Real-Time Operating Systems

For optimization of RTOS, we need a performance measurement baseline. RTOS-specific benchmarks like ThreadMetric can provide numbers on how some implementations are more or less suitable for time-critical applications.
