Abstract:High frame rate CCD (Charge Coupled Devices) and high speed DSP(TMS320C40) 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. With this testing system, the optical image can be converted into digital image for the 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.
Keywords:charge coupled devices  image processing  high frame rate  image sampling
