【摘要】：高速串行传输是当前高速数据传输的主流方式，广泛应用于各个领域，因此对高速串行传输的稳定性、可靠性及开发周期等方面提出了较高的要求。本论文结合科研实践，设计并实现了在稳定性、可靠性及开发周期方面具有明显优势的基于RocketIO的高速串行通信接口，该接口主要用于高速串行数据传输。本论文首先研究了高速串行收发器的工作原理、实现方法以及配置特点等，在此基础上，实现了基于RocketIO高速串行收发器的四种回环，，这些回环常用于测试和配置数据通路。然后，研究当前有关高速方面的理论，分析其工作原理，结合实际应用需求，提出了基于RocketIO的高速串行数据传输的整体方案，分模块研究与实现，最终在软件上实现了基于RocketIO的高速串行数据传输。最后，用Xilinx专用调试工具——在线逻辑分析仪（Chipscope pro）对该系统进行调试，采集PCB板上的数据，用Matlab恢复波形；用误码率分析仪（IBERT-InternalBit Error Ratio Tester）分析该系统的误码率，最终在硬件上实现了基于RocketIO的高速串行数据传输，误码率低至10-13，可靠性得到保证。基于RocketIO的高速串行数据传输具有稳定性高、可靠性高、开发周期短等优点，模块化、参数化设计思想使得该系统更新容易；丰富的接口资源使得该系统扩展容易；自定义传输协议的灵活性使得该系统被广泛应用。
[Abstract]:High speed serial transmission is the mainstream way of high speed data transmission at present. It is widely used in various fields. Therefore, high requirements for the stability, reliability and development cycle of high speed serial transmission are put forward. A high speed serial communication interface based on RocketIO is designed and implemented, which has obvious advantages in stability, reliability and development cycle. The interface is mainly used for high speed serial data transmission. In this paper, the working principle, realization method and configuration characteristics of high speed serial transceiver are studied. On this basis, four kinds of return loops based on RocketIO high speed serial transceiver are realized. These return loops are often used to test and configure data paths. Then, the current theory of high-speed data transmission is studied, and its working principle is analyzed. According to the practical application requirements, the overall scheme of high-speed serial data transmission based on RocketIO is put forward. Finally, the high-speed serial data transmission based on RocketIO is realized in software. Finally, the system is debugged by Xilinx special debugging tool, on-line logic analyzer Chipproscope, the data on PCB board is collected, and the waveform is recovered by Matlab. The bit error rate (BER) of the system is analyzed by IBERT-InternalBit Error Ratio Tester. Finally, the high-speed serial data transmission based on RocketIO is realized in hardware. The BER is as low as 10-13, and the reliability is guaranteed. High speed serial data transmission based on RocketIO has the advantages of high stability, high reliability, short development period, etc. The flexibility of custom transport protocol makes the system widely used.
