基于DSP和FPGA的数据采集系统设计

Design of data acquisition system based on DSP and FPGA

结合高速DSP和FPGA的特点,设计了一套数据采集系统,应用FPGA的内部逻辑实现时序控制,以DSP作为采集系统的核心,对采集到的数据进行滤波等处理,并将处理后的结果通过USB口传输到计算机。该系统具有电路结构简单、功耗低、数据传输方便等优点,可用于电压、电流、温度等参量的采集系统中。

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.
