摘　　要：针对目前对图像采集处理系统的高速性和便携性的要求,设计了一套基于DSP、FPGA和ARM9的实时图像采集处理系统。该系统主要利用FPGA的SoPC系统定制Nios Ⅱ软核处理器及相关外设IP核来完成图像数据的采集和存储。DSP通过EMIF接口和EDMA接口完成数据的搬移和图像处理的算法。ARM作为主机,通过HPI接口与DSP进行数据通信。结果表明,该平台工作性能稳定,处理能力强,能完成算法的数据处理并对数据实时显示,适用于自动循迹、模式识别等高速数据采集的应用场合。This paper presents a real-time embedded platform for image acquisition and processing, which is based on DSP, FPGA and ARMg, for the requirements about high-speed and portability. The design main uses SoPC of FPGA to customize NiosIIsoft processors and IP core to complete image data acquisition and storage. DSP takes charge of the algorithm and the data migration through EMIF and EDMA. ARM, the host, communicates with DSP through the HPI. The results of these experiments show that this architecture can complete the data processing algorithm and real-time display. It is stable and powerful. The system is suitable for the situations requiring high speed processing such as automatic tracking and pattern recognition.
