摘 要：In this paper,research on a high speed arc image sampling and processing system based on DSP has been done.A RS-422A interface has been used to sample high speed image,A TMS320C40 high speed DSP and high frame rate CCD are used as the sensor.The optical image can be converted into digital image in this image sampling and processing system efficiently,with the high speed DSP and the high speed memories,to improve the data transfer speed and receive the image data correctly,DMA data communication technology is adopted.The test result shows that this system is very effective for arc research.
