Abstract:

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 coll ection 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.
