Abstract

The data acquisition and transmission system is required to acquire data in real time and transmit in high speed and the size of it should be as small as possible.In order to meet the requirements above,a embedded data acquisition and processing system based on FPGA and DSP and USB controller architecture is proposed.FPGA is designed to serve as the controller of multichannel data acquisition and DSP is used to process the acquired data.The utilization of USB2.0controller is to realizes high speed transmission of data.The experiment results show that the designed system has high real-time property and stability.The sample rate can be up to 10MSPS.
