摘　　要：任意波形发生器是现代电子测量领域应用最为广泛的一种通用信号源;为了更好地满足人机交互,介绍了一套基于μC/GUI和SOPC技术的任意波形发生器人机交互系统设计方案;系统采用Avalon突发模式设计一个通用的LCD控制器,实现触摸屏为人机交互输入接口,分析并完成μC/GUI的移植,最后完成仪器的图形界面设计;整个系统采用SOPC技术集成到单片FPGA芯片内部,既降低开发成本,又提高系统的稳定性;实验结果表明基于μC/GUI设计的界面简洁友好,触摸屏操作方便直观,整个系统运行稳定,任务能够实时处理;该系统占用资源少,成本低,集成度高,稳定性强,具有一定的实用价值。Arbitrary waveform generator is one of the general instruments that widely used in modern electronic testing field. This article introduced a man--machine interactive system based on uC/GUI and SOPC in order to better meet user＇s demands. It designed a generic LCD controller that adopted Avalon burst--mode, completed touch screen as input interface, analyzed and accomplished the transplant of uC/ GUI, finally, completed graphical interface design. The entire system integrated into a FPGA chip that adopted SOPC, which not only reduced the cost, but also improved the stability. The experiment result shows that it designs simple and friendly interfaces based on uC/GUI, operates easily that adopted touch screen, run stably, real--time processing tasks. The system has a good ability of fewer resources, lower cost, higher integration, which has a certain practical value.
