Hardware/software partitioning of operating systems [SoC applications]

We present a hardware/software RTOS (real-time operating systems) generation framework for system-on-a-chip (SoC) applications. We claim that current SoC designs tend to ignore the RTOS until late in the SoC design phase. In contrast, we propose RTOS/SoC codesign where both the multiprocessor SoC architecture and a custom RTOS (with part potentially in hardware) are designed together. Thus, this paper introduces a hardware/software RTOS generation framework for customized design of an RTOS within specific predefined RTOS services and capabilities available in software and/or hardware (depending on the service or capability).
