| Abstract: | In this paper a PCI data transfer card is designed for synthetic aperture sonar(SAS) data acquisition,PCI9054 is used to bridge the local bus and PC104 plus and provide a high speed DMA channel,CPLD is used to implement tar- get read logic of local bus,dual port RAM is used to buffer the A/D data.Device driver under Linux for the card is tai- lored to meet the requirement of data acquisition.At last our design is verified by experiments,the actual transfer speed reaches 50MB/s. |
