基于FPGA的线阵CCD子图像提取模块的设计与仿真

Design and Simulation of Linear CCD Sub-image Module Based on FPGA

根据线阵CCD图像检测和识别系统的要求,分析线阵CCD图像与子图像的位置关系,采用"图像转置缓冲区"和读写状态机的处理方式,设计基于FPGA的线阵CCD子图像提取模块,具有FPGA资源占用少、逻辑清晰的特点。用MATLAB和Modelsim软件进行联合仿真,验证了设计的正确性。

According to the requirements of the linear CCD image detection and recognition system,this article analyzed the linear CCD image relation with the position of the sub-image,adopt "transposed image buffer" and the state machine approach, designed linear CCD image extraction module based on FPGA,it has the characteristics of FPGA resources occupy less,clear logic.In this paper, MATLAB and Modelsim software co-simulation,verify the validity of the design.
