The development of software for Electric Load Management Center (ELMC) is presented in this paper. Based on the embedded real-time operating system VxWorks, ELMC performs multiple tasks including periodic and aperiodic ones. While rate monotonic (RM) algorithm is still used to process periodic tasks, we propose a condition triggered algorithm (CTA) to schedule aperiodic tasks by using VxWorks's semaphore...
In embedded real-time operating system (RTOS) area, a hybrid algorithm (HRPP) based on Vxworks is presented. Periodic tasks are scheduled by round-robin scheduling; non-periodic tasks are scheduled by static priority-base preemptive scheduling. The communication between tasks is by semaphores. A controlling program used for the second power distribution accouterment (SPDA) is designed according to...
