Time-Triggered 프로토콜의 스케줄링을 위한 Multi Queue 기반 메시지 버퍼 설계

In the future, an intelligent car requires high level applications such as safety, convenience, reliability. Many automotive companies have chosen the CAN protocol for their in-vehicle networking system such as chassis network system because of its excellent communication characteristics. However, the increasing number of ECUs and the need for more intelligent functions. Recently, FlexRay protocol that is a time-triggered protocol has been introduced. And many automotive companies have been focusing on this protocol. However, FlexRay protocol requires the complex scheduling list and unique message buffer each static slot. This paper presents a design of FlexRay multi queue based message buffer and we evaluated its feasibility using simple H/W.
