Paper Abstract

For high-speed data stream from a high performance CCD image sensor, optimizing data channel and extending bus bandwidth are essential to ensure real-time storage of image, based on present computer architecture and SCSI technology. This paper put forwards a method of bypassing the main memory to directly transfer data from an image acquisition device to a SCSI hard disks array in this paper. Moreover, It describes the process of creating a high-speed data channel in detail. In order to simplify the structure of CCD image storage system, an embedded sample has been designed. A series of tests show that the storage rate will be up to 130MB/s if designed on embedded RTOS platform and 64-bit/33MHz PCI bus, so it can meet the needs of some high-speed CCD applications where speed and image quality are crucial.
