摘要：
In this paper, we show the performance comparison and analysis result among three RTOSes: the Real-Time Unit (RTU) hardware RTOS, 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 RTOSes. 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.
