Abstract
FlexRay is a new standard for network communication systems, 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 modules using specification and description language (SDL). Then, the system is implemented using Verilog HDL based on the SDL source. The FlexRay design is synthesised using Samsung 0.35 μm technology and the operating frequency is above 76 MHz. To validate our designed FlexRay system, it is combined with sound source localisation system in robotics applications. The integrated system is implemented using ALTERA Excalibur ARM EPXA4F672C3. The system operates successfully as demonstrated in experimentation.
