Rate monotonic scheduling algorithm (abbr. RM) is one of the main algorithms in real-time systems, but its operation efficiency is low relatively. In this paper, two-level scheduling method is used to improve the operational efficiency of RM algorithm, and the basic principle of computer processor in real-time system is analyzed, and the RM scheduling algorithm is implemented concretely. Considering the shortcoming of RM algorithm, a modified RM algorithm based two-level scheduling strategy is proposed. As a result, the performance and reliability of real-time system is increased, and the applicability of the method is widened.
