Implementation of FlexRay CC and BG Protocols with Application to a Robot System

摘要

FlexRay is a new standard of network communication system which has been developed for future automotive applications. FlexRay communication controller (CC) is the core of the FlexRay protocol specification. Bus guardian (BG) is an optional electronic component. In this paper, we first design the FlexRay CC and BG protocol specifications and function parts using SDL (Specification and Description Language). Then, the system is re-designed using Verilog HDL based on the SDL source. The FlexRay system was synthesized using Samsung 0.35 μm technology. It is shown that the designed system can operate in the frequency range above 76 MHz. In addition, to show the validity of the designed FlexRay system, the FlexRay system is combined with sound source localization system in Robot applications. The combined system is implemented using ALTERA Excalibur ARM EPXA4F672C3. It is shown that the implemented system operates successfully.
