高帧频CCD数据采集处理系统的设计

Design of High Frame Rate CCD Data Acquisition System

针对某高帧频CCD相机的设计要求,提出一种可行的CCD数据采集处理方法。由FPGA为CCD、A/D变换器提供控制信号,利用多通路数据传输的结构实现了高速图像数据的同步采样,并由高速A/D芯片AD9942实现数据的模/数转换。创新性地将控制信号和数据缓存集成在一片FPGA上,仿真结果能够很好地实现CCD高速数据采集处理。

In view of some high frame rate CCD camera′s design requirements,a feasible CCD data acquisition system is proposed.FPGA is used to provide control signal for CCD and A / D converter.Using the structure of multi-circuit data transmission and the high speed A/D chip AD9942 to realize the high speed image data synchronized sampling,integrating control signal with data cache in a FPGA.The simulation results can very good realize CCD high speed data acquisition processing.
