基于ARM的数码复印机CCD图像信号的高速采集存储系统设计

数码复印机CCD单元的正确驱动及信号的高速采集存储和处理，是复印机整个复印过程中至关重要的环节。介绍了一种基于ARM和高速A／D的数码复印机CCD单元信号的高速采集存储系统，其中用CPLD来设计CCD的驱动，以ARM为主控制器，完成对CCD单元、高速A／D转换单元、高速存储单元的整体控制，使整个系统能够真正地高速同步工作，完成CCD图像信号的高速采集存储。

Design of Digital Copier's CCD Image Signal High-speed Acquisition and Storage System Based on ARM

The correct driver,high-speed acquisition, storage, and processing of digital copier＇ s CCD unit plays a very important role in the whole copying process. This paper introduces a high-speed image signal acquisition and storage system of digital copier＇s CCD that is based on ARM. It uses the technology of CPLD to design CCD driver. The ARM as a main controller control,coordinate the CCD unit,high-speed A/D unit,and high-speed storage unit,it makes the whole system work in a high-speed and synchronous way, and then implements the high-speed acquisition and storage of data.
