The Design of DSP High Speed Data Acquisition System Based on USB2.0 Protocol

On the purpose of portable high speed data acquisition,a high speed data acquisition system based on USB2.0 protocol was developed.It used the TI's C6000 series DSPs as the core part and realized the high data transfer speed by the USB interface chip.Details about the HPI(host-port interface) of DSP,the GPIF(general programmable interface) and endpoints of USB chip,the firmware program of USB chip,the application program of PC host and so on were depicted.The acquisition system was applied to partial discharge on-line monitoring,and realized the detection and reconstruction of partial discharge signals.
