CPLD在图像采集与控制中的应用

CPLD at the application among image collection and Control

该文详细介绍了基于CPLD/FPGA技术的视频图像采集与控制的软硬件设计方法及实现方案。在该设计中,CPLD/FP-GA的主要功能是完成视频图像采样,对图像信号进行动态检测。本设计中的主控制器采用了ALTERA公司的CPLD芯片EPM7128SLC84,采用VHDL作为硬件描述语言,但是所编写的VHDL源程序既适用于CPLD器件,又适用于FPGA器件。

The article has introduced the design method and the realized scheme of software and hardware of video image processing system based on CPLD/FPGA technology. In the design, The main function of CPLD/FPGA is to finish the video image sampling, the signal development the examination. CPLD EPM7128SLC84 chip of Altera Company has been adapted in the design of the main controller and VHDL was utilized for hardware description, but VHDL source program written is not only suitable for CPLD device but also suitable for FPGA device.
