Abstract：In recent years，based on PCI bus high speed data collecting system is a developing direction of data gather and transmission technology.This paper encircle with PCI bus interface controller PCI9054,presents the hardware system design scheme,and respectively discusses the modules.The card which we designed have the characteristic of less capacity,high speed,back up the burst transmission of a great number of data,and have strong performance of anti jamming,the mostly application domain of this card is image manipulation. ?
