针对实际项目需求,在充分了解Camera Link接口协议和HDMI接口协议的基础上,给出了基于FPGA的Camera Link—HDMI高清视频转换器设计方案。选用Ahera公司的Cyclone IV系列FPGA器件,完成了转换器的电路设计和性能测试。结果表明,图像转换实时性好,色彩和图形无失真,满足设计要求。该方案是一种解决Camera Link—HDMI转换的有效方法,为相似的技术设计问题提供了有益的参考。
In order to meet one project requirements, based on fully understanding to the Camera Link protocol and the HDMI interface protocol, a design scheme of Camera Link-HDMI converter is presented. According to the scheme, one Cyclone IV device which is Ahera's FPGA device is chosen. And the converter is made and tested. The testing results show that real-time of the image conversion has been ensured. And colors and graphics of the image were without distortion. The design demand was met. The scheme is a method to take Camera Link-HDMI conversion, and may be a useful reference for similar techniques design.
