基于瞬时负载率的CAN总线系统调度分析

Scheduling Analysis Based on Instantaneous Load Rate in CAN Bus

针对CAN总线系统在Tindell等专家调度理论分析的基础上,利用瞬时负载率函数对总线系统调度理论方面的问题进行了进一步的讨论分析;结合BD改进算法利用瞬时负载率函数对总线系统的可调度性能进行判定.应用算例计算表明,采用该方法判定总线系统可调度性能得到的结果正确且过程简单便捷,对于CAN总线系统设计有很大的实际意义.

Based on the scheduling theory of Tindell and other experts for CAN bus system,the further discussions and analysis for system scheduling theory is studied supported by the instantane- ous load rate; the system scheduling function is judged by the improved algorithm scheduling using instantaneous load rate combinated with BD scheduling algorithm. Application example shows that this method of system scheduling determines the results correctly and the process is simple and easy. This has great significance to CAN bus system of designing.
