Design of FPGA-based high-speed multichannel speech signal acquisition system

摘要

Focusing on the actual situation of acquiring and dealing with speech signal in harsh environment, this article introduced the FPGA-based high-speed multichannel data acquisition system design. The system utilized FPGA as the Core Chips for the Control System to achieve A/D acquisition, data transmission, abstract storage and USB chip control. Experimental results presented that the system could complete high-speed data acquisition, mass storage, and communication function between USB2.0 and upper monitor.
