视频编码芯片TFP410的FPGA初始化

Design and Realization of Digital Display Interface Based on FPGA

基于FPGA在当今数字电路开发中灵活高效的平台作用,提出一种基于Altera公司FPGA设计而实现的嵌入式实时图像显示接口方案。采用FPGA配置视频编码芯片TFP410,将图像信息通过HDMI物理接口发送到外部显示设备,为后续高级图像处理做准备。重点介绍了TFP410外围电路设计及I2C配置实现方法。在QuartusⅡ平台上,采用SignalTapⅡ逻辑分析仪对系统进行时序分析,并给出了试验图片。该设计方案可靠,易于升级,可满足视频显示系统对实时性的要求。
