摘要
随着红外探测技术的高速发展,红外信号的实时处理面临着较大的挑战.在采用多单元与高帧频探测器的红外系统中,当使用较复杂的处理算法时,基于传统架构的信号处理平台已较难满足系统的实时处理要求.通用计算图形处理器(GPGPU)的出现与日益成熟为红外实时信号处理提供了良好的平台.根据红外系统中实时信号处理的特点,利用FPGA+CPU+GPU架构构建了一种新型红外信号处理平台,并进行了实际应用.结果表明,该平台能够胜任探测器单元数多、帧频高和算法较复杂的红外系统的实时信号处理任务.
With the high speed progress of infrared detector technology,the Real-time processing of infrared signals meets a biggish challenge.When executing more complicated processing arithmetic,the Signal Processing Platform based on trad framework is hard to meet the demand of real-time processing in the infrared system with a detector which has more cells and higher frame speed.With the developing of General Processing Graphic Processing Unit（GPGPU）,it provides the better platform for Real-time infrared signal processing.According to the characteristic of Real-time processing in the infrared system,a new type platform based on FPGA＋CPU＋GPU framework to process infrared signals was constructed and applied practically.The experiment results indicate that the platform is equal to the Real-time signal processing task of the infrared system in which the detector has more cells,higher frame speed,and more complicated arithmetic.
