摘　　要：应用Altera公司的Strati(TM)Ⅱ系列FPGA EP2S30F48415芯片和基于Camera Link接口的数码相机CV-A1OCL,设计实现了对高分辨率黑白数字图像进行拆分压缩、解压缩及PCI总线接入拼接恢复的系统。系统分为数码相片压缩单元、数码相片解压缩单元和基于MFC的图像拼接恢复程序。数码相片压缩单元完成对来自相机Camera Link接口数据的接收、缓存、图像数据压缩并发送,数码相片解压缩单元完成对接收到的已压缩的图像数据进解压缩,并将解压缩后的图像数据通过PCI总线传输至PC上显示。Employs EP2S30F48415 FPGA of Altera StratixTM II series and CV-A10CL camera with Camera Link interface ,this system implements the split-compression and decompression-combination based on PCI bus of a monochrome with numerous pixels. The system consists of image compression unit, decompression unit and MFC program for image combination. Image compression unit addresses receiving, buffering, split, compression and transmitting for image data. Decompression unit decompresses the compressed JPEG2000 data and transmits decompressed pixels to MFC program through PCI bus slot on PC main board.
