基于协处理器和动态时间片RM调度算法研究
Research on RM Scheduling Algorithm Based on Coprocessor and Dynamic Time Slice
摘要
Abstract
The coprocessor and the main processor are combined to form the multi-core processor system,which has the advantages of low power consumption and high performance. The heterogeneous parallel architecture can effectively reduce the burden of the main pro-cessor,enhancing timeliness and effectiveness of the system. In order to make full use of the advantages of multi-core platform,improve the scheduling efficiency and implementation method of real-time system,a new Rate Monotonic ( RM) real-time scheduling algorithm based on dynamic time slice is proposed. It combines the advantages of speed-adjustment scheduling algorithm and the round-robin scheduling algorithm. The new algorithm is applied to the wireless meter reading system. Experimental results show that the proposed al-gorithm makes the time of scheduling in complex communication environment obviously close to the ideal time,which is superior to the traditional algorithm.关键词
