| Abstract: | With the increasing performance,the test of DSP in an embedded system is more and more complex. High speed and low costinterface is necessary to communicate with host computer. The HPI interface can send data without disturbing the main program of DSP.USB2.0 can transmit the data to PC with high speed. HPI-USB2.0 link combines the excellences of HPI and USB2.0,and satisfies theDSP test requirement with simple hardware and software. |
