基于高速CCD器件信号采集的控制DMA传输
DMA system controlled by single chip microcomputer for signal collecting of high accurate CCD Output
【摘要】 针对高速度CCD器件输出信号数字化处理后数据存储速度要求高,单片机控制存储难以满足要求的问题,提出一种基于高速A/DTLC5510的DMA(directmemoryaccess)单片机控制系统有效解决了该问题。该系统数据采集速度可达167ns/次。
【Abstract】 In this paper, DMA(direct memory access) based on high speed A/D TLC5510 controlled by the single chip microcomputer is introduced. Trough this method the problem of high speed data acquisition of di-gitized output of CCD is solved. The speed of data acquisition for this system can reach 167ns/every time.
