【摘要】：在现代数据处理和通信中,FPGA芯片已经被广泛使用,随着FPGA芯片的集成度越来越高,目前已经集成了ARM、 DSP等硬核,再结合FPGA在并行处理、实时性和低功耗的优势,FPGA会在应用前景会更加广阔。本论文从硬件和软件两大部分详细描述了整个系统的设计与实现,硬件系统部分主要是对基于FPGA各个硬件模块的原理图设计进行了详细的说明,完成了系统硬件电路板PCB的设计与调试；软件部分主要是从数据采集、内部通信和外部组网通信三个部分阐述了具体的实现,包括原理的设计、FPGA程序的开发、网络拓扑的实现等。本论文主要一方面解决的是数据采集的问题,主要是如何通过FPGA实现数字、模拟信号的采集,并对不同的信号采用不同的隔离措施,屏蔽相应的干扰。本论文另一方面解决的是通信问题,主要是集成了FPGA和ARM核的SoC芯片内部通信问题和外部通信组网的问题。SoC芯片内部通信问题,主要是如何使用Avalon这一内部总线,包括Avalon总线的配置、HPS的启动流程和FPGA内部通信模块的设计。系统间组网通信主要是如何采用冗余的光纤通信实现主备链路协议制定与切换。基于此设计的数据采集与通信系统,不仅具有高实时性、并行处理的能力,而且简化了硬件了电路的复杂度,提高了系统的可靠性,为相关项目提供了新的设计思路。
[Abstract]:FPGA chips have been widely used in modern data processing and communication. With the increasing integration of FPGA chips, ARM, DSP and other hard cores have been integrated, and then combined with FPGA in parallel processing. The advantages of real-time and low-power FPGA will be more widely used. This paper describes the design and implementation of the whole system in detail from two parts of hardware and software. The hardware system mainly describes the schematic design of each hardware module based on FPGA. The hardware PCB of the system is designed and debugged, the software part mainly elaborates the realization from three parts: data acquisition, internal communication and external networking communication, including the development of FPGA program. The realization of network topology and so on. On the one hand, this paper mainly solves the problem of data acquisition, mainly how to realize the acquisition of digital and analog signals by FPGA, and how to use different isolation measures to shield the corresponding interference. On the other hand, this paper solves the problem of communication, mainly the internal communication problem of the SoC chip integrated with FPGA and arm core and the problem of external communication networking. The main problem is how to use the internal bus of Avalon. It includes the configuration of Avalon bus and the design of internal communication module. How to use redundant optical fiber communication to establish and switch the main and backup link protocols is the main method of inter-system network communication. The data acquisition and communication system based on this design not only has the ability of high real-time and parallel processing, but also simplifies the complexity of the hardware circuit, improves the reliability of the system, and provides a new design idea for the related projects.
