Abstract

The holistic schedulability analysis which takes the processor scheduling and communication scheduling into consideration simultaneously describes the behavior of the distributed system more sufficiently. Based on the application of holistic schedulability analysis to the distributed CAN bus system, an improved holistic schedulability algorithm is presented according to the characteristic of CAN bus. The best-response time of tasks and the response time with probability bit-stuffing of CAN message is introduced to the improved algorithm. To prove the validity of the improved algorithm a case of example is given, which manifests that the algorithm makes more full use of the resource.
