PAGE 摘 要 SOPC触控屏接口驱动设计紧跟嵌入式系统发展趋势，采用一种新的嵌入式系统设计技术——SOPC(片上可编程系统)技术进行的触控屏接口驱动设计产品开发。TFT触摸屏具有电压低、功耗小、易集成、轻巧便携以及显示效果好等突出优点，现已广泛应用于各种显示领域，在人机交互中扮演着重要的角色。 本文设计的是基于SOPC触控屏接口驱动。该驱动设计分为硬件开发和软件开发两个流程。通过软件控制硬件电路触控屏的显示。 本设计采用Altera公司的CycloneIII系列的FPGA芯片配置Nios II处理器，采用Verilog语言编写触控屏接口驱动；在SOPC用户自定义IP核添加设计的驱动组件；使用Altera公司提供的Quartus II 8.0和Nios II 8.0作为调试环境；完成了设计任务，达到了预期的效果。 关键词：Nios II；Quartus II；FPGA；Verilog；SOPC Abstract The SOPC touch screen interface drive design follows embedded systems development trend, using a new method of embedded system design technology -- the SOPC (chip programmable system) technology for touch screen interface drive design product development. TFT touch screen with voltage, low consumption, easy integration, lightweight portable and display prominent advantages effect is good, has been widely applied in all kinds of display field, in human-computer interaction plays an important role. This design is based on the SOPC touch screen interface drivers. The driver design into hardware development and software development two processes. Through software control hardware circuit touch screen displays. The system uses Alteras FPGA chip configuration CycloneIII series NiosII processor, The touch screen is base on Verilog language preparation interface drive; Using the SOPC user-defined IP nuclear add design driver components ; using Alteras Quartus II 8.0 companies and Nios II 8.0As a debugging environment; to complete the design task to achieve the desired results.
