基于FPGA和DSP的红外图像信号发生器设计与实现

Design of infrared image signal generator based on FPGA and DSP

用EP2C35F484-FPGA和TS201-DSP作为硬件架构,设计了一种红外图像信号发生器,用于模拟实际红外探测器的像元输出及时序产生功能,从而可作为红外图像信号处理器调试和开发的信号源。利用数据压缩及插值、制式转换等方法实现了红外图像信号源的模拟视频及数字视频两路输出。

By using the EP2C35F484-FPGA and TS201DSP as the hardware architecture, the designed infrared image signal generator can emulate the output character of pixels and the timing sequence of the infrared detector. So, it can be used as the signal source of infrared image signal processor under debugging and investigation conditions. Also, the analog and digital video outputs are produced by using the data-compress and value-insert methods.
