Abstract – 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.
