Abstract :
The use of a Real-Time Operating System (RTOS) is now quite common in embedded systems because of the requirement for multi-tasking. We present the details of our port of the popular MicroC/OS-II RTOS to an avionics platform based on a PowerPC 7410 processor with multiple peripherals including RS422, MIL1553, digital IO and timers. Also, the systematic testing that we have carried out to validate the port is also presented. Further, detailed performance measurements have been carried out, and we also compare the performance of our MicroC/OS-II port with that of RT-Linux on the same platform.
