The main content of the dissertation is designing and realizing the total scheme and frame of system software. The module of the input and output is designed by using the generally I/O of the multichannel buffered serial port to simulated the communication of I~2C bus. The Ping-Pong buffer is brought forward to resolve the problem of the data rate matching. The logic switch function is designed in the programmed logic devices. The data transmission rate is improved by using the DMA and the dual buffer mechanism. The system program self-loading is realized by the design of the self-leading program. Lastly, the dissertation analyzes the characteristic of LLL video and experimentalize with some typical image processing algorithm.
