微型系统长距离DVI信号传输的FPGA实现

摘要

为了实现长距离DVI信号传输，采用内部集成均衡功能的专用解码芯片SiL1161和FPGA软件配置方法，从而简化了硬件设计的复杂性以及节省了PCB设计成本。针对FPGA特点，对I2 C总线以及配置算法进行了相关研究，并进行仿真验证。实验结果表明，常规长度以及长度长达15m标准电缆的DVI信号传输试验，获得信号质量无缺失，无失真，该设计方法具有效率高、通用性好、硬件成本低、可靠性高的特点，特别适合微型系统视频转换器的开发。%In order to complete longer distance DVI signal transmission, SiL1161 decoder contained equalizer function and method of FPGA software configuration were presented in the paper to simplify complexity of hardware with cost-effective applica-tion.I2C Bus and configuration algorithm for software was studied in the paper according to feature of FPGA ,and simulation and validation were provided in the paper.Experimental results show that the length of cable can reach 15 meters to perform DVI signal transmission experiment and the DVI signal is no-distortion and no-deformity.The design method is of high-efficiency,good general-ity,low cost and high reliability ,thus suiting to develop video converter for micro-system .
