The Research and Application of USB Interface in the Design of FPGA

Article Preview

Abstract:

The research of the communication between USB interface chip PDIUSBD12 and the data sampling system which is based on FPGA is introduced. And it gives a design method of a data acquisition system based on USB interface and FPGA technology. Both the logic relation and communication between USB and FPGA are studied. And it also provides the design method of the driving and application program. Finally, the simulation result proved that the method can not only achieve great agility and high speed, but also make the data communication interface rapidity and simplicity. Key words: USB; FPGA; data sampling; driving program; application program
