Study on high speed sampling and processing of dynamic image with TMS320C40

In this paper, high frame rate CCD (Charge Coupled Devices) and high speed DSP (TMS320C40) are used as the sensor of image, a advanced system of high speed image sampling and high speed data transfer with RS-422A have been designed. Using this testing system, the optical image can be converted into digital image for convenience of computer processing. With the high speed DSP (TMS320C40) and memories as the core of the testing system, the interface of high rate data buffer between computer and the CCD camera has been implemented. Meanwhile the double CPU system of the communication with DMA technology is made of the DSP chip and host computer.
