Description: a design of ultra high speed FFT processor based onFPGA is developed in this paper. At present we always use radix-2 and radix-4 tocarry out FFT. When the scale of FPGA is panding,it s possible to implement higher radix FFT. This topic uses Stratix II of Altera company to carry out a
processor of radix一16 FFT.In this design, radix-16 FFT is carried out by radix-2FFT, The design uses rational time sequence arrangement to make butterflycomputing,data transformation and memory coincide.In order to avoid the
bottleneck,pipeline pattern is used,this method acceletates the operating.Thescheme realizes the 4096-points and 256-points FFT, their operation clocks canboth reach above 100MHz. Among them ,the throughput of 256-points FFT is up to1.36GHz.
