Abstract

This paper introduces an implementing method of a high-accuracy real-time data acquisition system.It introduces how to implement interface between general programmable interface(GPIF)of high-speed USB peripheral controller EZ-USB FX2(CY7C68013)and FIFO.It presents the feature of flow state of the GPIF,flow state registers and how to use them,and illustrates how to perfect the firmware.This method can handle bursts of data and meet burst access timing to the external FIFO efficiently.
