【摘要】 以DSP TMS320C6205为核心处理器,设计了一种基于复杂可编程逻辑器件(CPLD)和DSP的实时图像采集系统.在介绍系统组成原理的基础上,重点讨论了CPLD在系统中的设计方法和工作流程,包括图像采集系统控制设计、图像传输控制设计等.系统采用SAA7113和CPLD完成了无DSP干预的图像采集与存储,通过DMA实现图像传输.实际应用表明,这种设计具有功能集成,结构实现简单,程序修改方便等优点,能得到满意的图像结果.更多还原

【Abstract】 A real time image acquisition and processing system is designed using DSP TMS320C6205 as it is key processor.The principle of imaging system is introduced.The application of CPLD is expounded in detail,such as image acquisition and delivery control logic of CPLD.The advantage of this method is function integration,simple realization and easiness to modify.更多还原
