Design of data acquisition system based on DSP and FPGA

A set of data acquisition system which combined characteristics of high speeding DSP and FPGA was developed.The internal logic of FPGA was used to control time sequence.And it took DSP as the core to read the acquisition data,filter and transmit data by USB interface.The system has a simple circuit structure,low power consumption,data transmitting convenience and so on.It can be used as the acquisition system of voltage,current and temperature parameters.
