摘　　要：基于ADI公司Blackfin533 DSP强大的图像处理能力及专用的并行外设接口,快速实现了图像数据的传输和JPEG静态图像压缩编码并通过以太网进行数据传输。通过改进SDRAM的读写数据方式以及利用Blackfin特有的汇编指令及内核架构,有效提高了采集、压缩速度,实现了高分辨率的图像监控系统的设计。Image processing and transmission and the JPEG still picture compression algorithm are speedily implemented based on the Blackfin 533 DSP,which is powerful in digital image processing and owns a parallel peripheral interface, and image data transmission is based on the Ethemet. The speed of image collection and compression is improved effectively,and the design of the monitoring system for high-resolution images is realized by ameliorating the mode of writing and reading operations of SDRAM and by using the unique assembly instruction set and the kernel framework of the Blackfin chip.
