| Abstract: | This paper describes a high-speed microcomputer data acquisition system which is comprised of DMA controller. It can gather the output signals from imaging CCD, and the high-speed data from other peripheral devices as well. The transfer of the sampling data is carried out without the interference from CPU. The system has the advantages of simplicity in configuration, flexibility in application, highness in transfer rate and price performance. (5 illus., 1ref.) |
