μC/OS-II based RTOS kernel

Abstract

With the development of embedded technology, more and more security critical tasks appeared in embedded application fields, which requires higher reliability of the system. ARINC653 are multiple tasks within a partition; partition system needs to provide partition scheduling and task scheduling. But lacks the comprehensive research on security guarantee and resource reservation for the partitions. A high-reliable, real-time embedded operating system kernel is introduced in this paper. The partition scheduling algorithm in this paper can prevent tasks in low critical level partition overtake tasks in high critical level partition when time resource is enough, while providing high level of system throughput and task schedulability. Access control algorithm can complete judgment of access control permission within time. It guaranteed real-time system with strong information security.
