摘　　要：为改善红外焦平面阵列成像质量,提出了以高速数字信号处理器为核心的红外焦平面实时图像数字处理系统,介绍了红外成像系统的结构并给出了系统的硬件实现框图,对系统工作流程和FPGA的控制逻辑及DSP响应中断实现数据转移及存储进行了分析。按作用划分为8个功能模块,详细讨论了3个功能模块的硬件实现和软件设计。In order to improve the imaging quality of Infrared focal plane （IRFPA） detectors, an infrared image digital processing system was proposed. The structure of infrared imaging system and the hardware realization block diagram were introduced. Entire processing flow of system and control logic of FPGA and DSP control and interrupt respond were analyzed. The system was compartmentalized into eight function modules according to its functions. The hardware realization and software design of three function modules were discussed in detail.
