摘要
为了提高FlexRay总线的静态段带宽利用率和实时性,推导FlexRay总线静态段的时间优化模型,得出最优静态时隙长度,在进行静态帧的负载段分割处理后,分析静态段的带宽利用率,提出以静态帧的总响应时间最小为优化目标的一种静态段优化调度方案,数值实验验证了优化的合理性。
An optimization model for the static segment of FlexRay network filed bus is deduced to improve bandwidth utilization and real time performance of the static segment of FlexRay communication protocol. The opti- mal slot length of static segment is given, the load length of static frame is cut up, and the network bandwidth utili- zation of static segment is analyzed. An optimal scheme for static segment is put forward to minimize the total re- sponse time. Numerical experiments verify the feasibility of optimization.
