摘　　要：提出了一种以Altera特有的基于通用FPGA构架的软CPU内核Nios Ⅱ为控制核心的图像采集系统的设计方案,完成了系统设计并进行了相应测试。所设计的图像采集系统可扩展性强,在不修改系统硬件的前提下,只需对NiosⅡ主程序及上位机做适当修改,便可使该系统具有一定的图像处理功能或作为不同应用系统的前端图像采集子系统。A design of image acquisition system which used Altera＇s unique soft CPU core Nios II based on a common FPGA architecturex as control core is presented in this paper. System design is completed and realization function is tested. The image acquisition system has good scalability. Without modification to the system hardware, the only appropriate modifications to the Nios main program and PC, can make the system has a certain image processing functions or as a front-end image acquisition subsystem different application system.
