摘　　要：在JPEG2000专用编解码芯片ADV212的基础上,设计了以FPGA与ADV212为核心的彩色图像数据实时压缩系统。系统以FPGA为主控单元实现了对图像数据的接收、压缩、发送,对ADV212寄存器进行了配置、数据输入,并将压缩数据实时上传到上位机。经过实际测试,该系统满足对彩色图像压缩实时性的要求,且系统稳定,失真度小,具有较高的实用价值。On the basis of the decoding chip ADV212 dedicatedly used for JPEG2000,a color image data real-time compression system taking FPGA and ADV212 as its cores was designed.The FPGA is taken as the main control unit of the system to receive,compress and send the image data.The ADV212 register is configured,and the data is input into it.After that the compressed data is uploaded to the host computer in real time.The actual test results show that the system can meet the realtime requirement for the color image compression,which is stable,and has small distortion and high practical value.
