Implementation Of Digital Camera System Based On USB And Asic Design Of USB Interface

The Universal Serial Bus is the most compatible serial bus interface with the greatest transmitting speed at present which was put forward by Compaq, DEC, IBM, Intel, NEC and Microsoft in Jan 1996.This paper mainly deals with the definition of Universal Serial Bus in computers and describes in detail the process of digital camera system design by using USB. This system takes advantage of the high rate of data transmission and hot attachment of USB to meet the requirement for real-time transfer when high quality image processing is performed.In the process of digital camera system design, full use is made of the technique of CPLD, which makes hardware design improved on the basis of a great amount of soft simulation and make modification of control circuits in the process debugging more convenient.
