基于FPGA多路机载冗余图像处理系统的设计与实现

摘要

The decoding,coding,real-time process and output display of multi-channel DVI video redundancy signal pro-cess system is realized by using FPGA as core processor. Furthermore,the addition of signal channel to redundant design makes the system more stable and reliable. The circuit not only has a simple design,but also has better expandability and agility. The actual testing results indicated that the system can process high-definition video with 24bit true color,1600×1200 resolution and 60Hz refresh rate smoothly,and it is reliable,stable and practicable.%采用以FPGA作为核心处理器，实现了对多路DVI视频冗余信号的解码、编码、实时处理以及输出显示，并且信号通道增加冗余设计，因而加强了系统的稳定性和可靠性。电路设计简洁，具有较强的灵活性和扩展性。通过实际测试结果表明，系统能够流畅地对1600×1200分辨率，60 Hz刷新率，24位真彩色的高清视频进行实时处理，其系统可靠、稳定，实用性强。
