Abstract

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 HRPP. The program is implemented in Vxsim integrated in Tornado2.2. The simulating result shows that the algorithm is reliable and under the condition of unknown time parameters, tasks switching time is limited in the microsecond.
