Real-Time Operating System (RTOS) is a very useful tool for developing the application on embedded boards with least software development effort. Though number of RTOS products are available in the market, uC/OS-II is a freeware with minimum facility and more popular among the hobbyist, researchers and small embedded system developers. The uC/OS-II supports preemptive scheduling which is not efficient with respect to processor utilization. As a result, this may lead to missing deadline of the task assigned and hence may cause system failure.
