- W2358415050 abstract "In order to solve the speed and design cost bottleneck of digital spectrum analyzer,a design method of high speed FFT processor based on FPGA was proposed which CycloneII FPGA EP2C35F672C6 chip was used to achieve the processor.The processor adopts the method of decimate in time Radix-4 algorithm.The FFT butterfly computing unit was designed by ameliorative CORDIC pipeline structure and dual-port RAM was used.The entire system was designed by VHDL and tested by using the simulation and hardware testing tool.The accuracy of design has been confirmed by comparison between the simulation result and the calculating result of MATLAB.It shows that the total simulation time of the 1024 points FFT is 45.6 μs,when operated at 90 MHz clock.The design satisfies the real-time requirement of the digital spectrum analyzer system,solving the conflicts between the real-time and resource occupied of the system.And the design is in the non-use of IP core,which greatly reduces the design cost." @default.
