Analysis of Time-triggered Architecture Bus

Time-triggered architecture has its own unique structure characteristics such as high resource utilization ratio,accurate system diagnostic and excellent composability can entirely satisfy modern communication system's requirement of being predictable,reliable and real-time.This paper mainly concentrate on two typical kinds of time-triggered bus which are TTP / C and FlexRay.Analyzed and compared through their node structure,data transmission,clock synchronize aspects,summed up and considered that,TTP / C will be widely used in safety-critical control system for its outstanding safety data transmission mechanism and FlexRay could also make an important role in the future distributed systems with its unique high flexibility.
