Abstract: Because of the capability of real-time processing and the character of open source, T-Kernel has occupied more than half in the global microprocessor’s operating system market share. This paper analyzes the task states and the scheduling mechanism of T-Kernel, and gives its scheduling opportunity and scheduling algorithm. From the real time character of the embedded real time operating system, the advantages of the scheduling mechanism are pointed out.
