摘要本文介绍了SRIO标准以及物理层、传输层、逻辑层协议,介绍了通过SRIO接口进行通信的原理和实现方法。基于SRIO实现FPGA与DSP高速通信的方法分为两大部分:首先是硬件设计,DSP作为主处理器,FPGA为协处理器,由于二者信号处理速率存在很大差异,因此需要通过收发器来实现二者互联,硬件部分包括信号转接板,SRIO接口硬件设计。其次是软件调试,方案一是基于FPGA设计SRIO各层通信协议,驱动SRIO接口硬件电路。由于方案一开发时间较长,此次我们采用方案二,即采用Xilinx-5开发板自带的SRIO IP内核,通过配置SRIO IP内核实现SRIO端口功能。分别配置并驱动Xilinx-5和TMS320C667的SRIO 端口来实现数据通信。9379

Title High Data Transmission System Design Between DSP and FPGA Based on the Serial Rapid IO
Abstract
This paper introduces SRIO standard as well as the physical layer, transport layer, logic layer protocol. Introduced the principle and Realization method of the communication with the SRIO interface. The communication method is pided into two parts. In which the Hardware designing comes the first .The DSP works as the main processor and the FPGA works as a coprocessor. Because of the different rate between the two device, a transceiver is needed to achieve the two interconnection. The hardware part comprises a signal adapter plate and a SRIO interface .Secondly is the software debugging. One of the design schemes is write the SRIO layer communication protocols to derive the SRIO interface. However ,it takes too much time ,so the other design scheme is adapted. Using SRIO IP kernel of the Xilinx-5 development board, by configuring the SRIO IP kernel to derive SRIO interface. Configuration and driving the SRIO of Xilinx-5 and TMS320C667 respectively to realize data communication.
