基于ARM和FPGA的CCD信号采集系统设计

Design of CCD signal acquisition system based on ARM and FPGA

为了构建数码复印机CCD单元的驱动及输出信号的高速采集、存储、传输和处理系统,应用FPGA完成CCD驱动和FIFO模块的设计。采用ARM为主控制器来完成对CCD单元、高速A/D单元、FIFO模块、高速存储单元和USB通讯的整体控制,构成了高速的数据采集、存储、传输和处理系统,实现了CCD图像信号的高速采集存储。经过上位机的图像处理测试平台,验证了基于ARM和FPGA的CCD信号采集系统设计的正确性和稳定性。

In order to build a driver of digital copier＇s CCD unit and a system of CCD output signal＇s high-speed acquisition, storage, transmission and processing. The article uses the technology of FPGA to design CCD driver and FIFO module. It makes ARM as a main controller control, coordinate the CCD unit, high-speed A/D unit, FIFO module, high-speed storage unit and USB transmission. They constitute a high-speed data aequisition, storage, transmission and processing system to complete CCD image signal＇s high-speed acquisition and storage. At last, using the testing platform of image processing has verified the correctness and stability of CCD signal acquisition system based on ARM and FPGA.
