Distributed System Data Link Hardware Platform Design

Distributed system plays an irreplaceable role in the fields such as target detection, target monitoring and distributed computing etc. It draws more and more attention from researchers. In this paper, the research objectives are wireless distributed acquisition and processing system, and mainly the paper explores the design and implementation of the hardware platform for distributed systems, including hardware design and hardware programming design.Hardware Platform Design mainly consists of the receiving analog front-end of underwater tranducer, receiver, signal acquisition, wireless AP communication circuit. For the realization of a weak signal acquisition, the Simulation system uses a variety of methods of improving noise ratio, adding gain control to achieve design goals. Through the cooperation of FPGA and DSP, the Digital system achieve gain control, data acquisition and wireless communications. On the basis of that, there is a certain space reserved for system upgrading.Hardware Programming Design is based on the hardware platform, mainly for the purpose of smooth flow of data chain. It includes FPGA and DSP programming design.FPGA programming mainly consists of three parts, namely, data collection, data cache, and DSP communications interface. DSP programming includes two parts:the receiver gain control andTCP/IP communication design.This paper has tested the overall fucntions of distributed hardware platform. The testing results were analysed and revised. The results show that the system runs properly and achieves the expected goals.
