摘　　要：随着电子技术的不断发展,可编程片上系统(SOPC)逐渐成为系统开发重要的方向。介绍了先进的SOPC平台VIRTEX-4的基本结构和特点,以及基本开发流程,并根据红外相机控制的实际需求,采用1553B总线与上位机实现指令和数据通信。在内嵌的PowerPC硬核中解析指令,FPGA中的控制功能单元根据指令对相机输出控制时序,完成控制功能,并以低电压差分信号(LVDS)方式采集和传输相机图像数据。相对传统的方案基于SOPC的控制模块具有高性能,低功耗,高集成性和灵活性的特点。With the development of electronic technology, System On Programmable Chip （SOPC） has became an important direction of system development. This article describes the basic structure and characteristics of an advanced SOPC platform VIRTEX-4, and the basic development process. Based on the actual demand of infrared camera control, the 1553B bus is adopted to realize instructions and data communications with host computer. After Analyzing the instruction in the embedded PowerPC hard core, the function units in the FPGA output control timing according to the instruction and use low-voltage differential signaling （LVDS） interface to transmit camera image data. Compared with the traditional method, this control module based on SOPC has characteristics of high performance, low power consumption, high integration and flexibility.
