Abstract :
In this paper, we show the performance comparison and analysis result among three RTOSs: the real-time unit (RTU) hardware RTOS (real-time operating system), the pure software Atalanta RTOS and a hardware/software RTOS composed of part of Atalanta interfaced to the system-on-a-chip lock cache (SoCLC) hardware. We also present our RTOS configuration framework that can automatically configure these three RTOSs. The average-case simulation result of a database application example on a three-processor system running thirty tasks with RTU and the same system with SoCLC showed 36% and 19% overall speedups, respectively, as compared to the pure software RTOS system.
