| Abstract: | In this paper, the design of voice communication interface of USB (Universal Serial Bus) based on DSP (Digital Signal Processor) is introduced.USB can be used to exchange data between DSP and PC, through which PC can command andcontrol USB device,can transmit and receive sound isochronous data to and fromUSB device. In this design, three kinds of USB digital transmission mode have been used: control transfer,interrupt transfer,isochronous transfer. They have different roles in the design. |
