The Porting of Real-Time Operating System uC/OS-II on MCS-51 Series of MCU

The powerful muC/OS-II is based on the priority preemptive real-time kernel which simultaneously provides task management, time management, memory management and communication between the tasks and functions can be ported and reduced freely. This paper analyzes the structure of muC/OS-IIpsilas kernel and its code, and introduces how to porting muC/OS-II to MCS-51 Series of MCU by means of establishing working stack, simulation stack, task stack and so on. At last, a test program is provided to prove the success of the porting.
