Adopting Very High Speed Integrated Circuit Hardware Description Language to Realize FFT
Cong Guan · Harbin Ligong Daxue xuebao · 2003
At present, FFT arithmetic is widely applied in the disposal of the data signals, which is disposed by software. On the basis of FFT arithmetic, Very High Speed Integrated Circuit Hardware Description Language (VHDL) and Field Programmable Gate Array (FPGA) are adopted to build arithmetic model and realize the function. After running, what has been gained is high speed about 10% -20% in the disposal of the data signals, reliability and stability of data.
