High-speed real-time signal processing system design and implementation based on FPGA
Jianhe Du, Zengyong Luo, Junfeng Wang · 2011
People usually adopt DSP and ARM for the signal gathering and processing. But many functions of DSP and ARM complete depending on software, the entire software's movement needs to account for the sampling time a part and they can't control complex periphery hardware circuit logic very well. Those Cause them having very big flaw in high speed data gathering and processing. A Field-programmable Gate Array (FPGA) has timeliness, good controllability and the quick processing speed characteristics. In this topic, we have designed a new high-speed signal acquisition board based on FPGA and use FFT ip core in FPGA to make spectral analysis with the digital signal of the board's output .This article Introduces our designed high speed real-time signal processing system based on the FPGA. We have verified its good operating performance through Actual experiment.
