摘　　要：针对某图像跟踪系统的通信需求,提出了一种在FPGA(现场可编程门阵列)上实现串口与链路口联合通信的方法;首先阐述了串口通信和链路口通信的基本原理,然后介绍了FPGA平台的硬件组成,重点对实现联合通信的各部分模块进行了说明;整个系统结构采用模块化设计,适用于自顶向下的设计方法;最后,在QuartusⅡ8.1平台上运用VWF(矢量波形文件)对各部分模块以及整个联合通信系统进行了仿真,其中"接收数据"由人工设定,观察到的"发送数据"与其一致,验证了设计的正确性和可靠性;该方法已成功应用于图像跟踪系统中。According to the communication need of an image tracking system, a mehod of serial port and link port uni--communication based on FPGA （Field Programmable Gate Array） was proposed. Firstly, the basic principles of serial port communication and link port com- munication were described. Then the hardware components of FPGA platform were introduced, and every module for the realization of uni-- communication was particularly described. The modular design method was used in the whole system, which is suitable for top--down de- sign. Finally, simulations of every module and the whole uni--communication system were done based on VWF in Quartus II 8. 1, in which the ＂Received Data＂ was set manually and the ＂Transmitted Data＂ was consistent. This design was verified correct and reliable by the simula- tions and this method has been successfully applied to image tracking system.
