摘　　要：提出一种CPLD和Cortex-M3相配合的视频采集控制系统的设计方法。以ARMv7中的Cortex-M3作为CPLD控制芯片,使用EPM7128作为主控芯片,对视频解码芯片SAA7111A进行视频数据采集,具有适应性和灵活性。介绍一种高效率、低功耗的视频采集控制系统,详细论述了软硬件的设计和实现方案。采用VHDL语言编程的仿真结果表明了该系统在高速下的顺利运行。This paper introduces a designing method for video data acquisition control system based on CPLD and Cortex-M3. The system uses Cortex-M3 in ARMv7 as the CPLD control chip and uses EPMT128 as the main control chip and conducts video data acquisition from video decoder chip SAA7111A with both adaptability and flexibility. The paper introduces a kind of video acquisition control system with high efficiency and low power consumption, and gives the discussion in detail the software and hardware design and the implementation scheme. The results of simulation with VHDL language programming demonstrate the smooth running of the system in high-speed.
