A REVIWE ARTICLE OF FPGA DESIGN FUNDAMENTAL AND SERIAL COMMUNICATION TECHNIQUE

Communication and interoperation are critical to modern industry. A reconfigurable intelligent gateway based on ARM and FPGA is proposed on the basis of current situation and developing trend of protocol converting to achieve communication and interoperation among heterogeneous field bus systems and TCP/IP network. The functional block diagram, hardware architecture, software structure and protocol converting and communication model of the gateway are presented. The proposed gateway has a strong intelligent control ability, flexibility, reliability, fast conversion speed, consolidated device description and upper-level interface. It can also be updated online, and used as protocol converter or stand-alone intelligent controller, and has great theoretical significance and practical value in the field of heterogeneous networks communication and interoperation.
