摘　　要：针对目前PC算法无法实现图像实时处理以及固定硬件平台很难实现算法修改或者升级的问题,设计一种基于SOPC可重构的图像采集与处理系统,实现了图像数据的片上实时处理以及在不改变硬件电路结构而完成算法修改或者升级的功能。此系统围绕两块Xilinx FPGA芯片进行设计,通过FPGA以及其Microblaze 32 bit软核处理器和相关接口模块实现硬件电路设计,结合FPGA开发环境ISE工具和EDK工具协作完成软件设计。由于采用SOPC技术和可重构技术,此设计具有设计灵活、处理速度快和算法可灵活升级等特点。A reconfigurable image acquisition and processing system was designed based on SOPC against the existing problems that PC algorithm can not achieve real-time processing right and it is difficult to achieve algorithm changes or upgrades in a fixed hardware platform,real-time image data processing on-chip and algorithm modified or upgraded functions without changing the hardware circuit are realized.This system is designed around two Xilinx FPGA chips and completed hardware design via FPGA Microblaze 32 bits soft core processor and associated interface module,completed software design combined with FPGA development environment ISE and EDK tools.As a result of SOPC technology and reconfigurable technology this design has the characteristics of design Flexibility,high processing speed and flexibility to algorithm upgrade.
