摘　　要：针对目前靶场光学测量设备大量使用数字CCD相机,设计基于SCSI接口的高速数字视频存储系统,采用PC机作为硬件平台,用ASPI指令直接在数字采集卡和SCSI适配器之间通过64bitPCI总线实现数据传输。在实际应用中可实现带宽为100MB/s的数据存储,取得了预期效果。The design of high speed digital video storage system based on SCSI interface is discussed because CCD digital cameras are widely used in the field of optical measurement. This system uses PC as hardware platform and transfers data between data capture card and SCSI host with ASPI commands. According to application the bandwidth can exceed 100MB/s and the expected result is obtained.
