Title: Implementation of Floating FFT Based on VHDL Language
Abstract: With the development of integrated circuit,the Electronic Design Automation(EDA) technology has became an important design method of digital circuit and Digital Signal Processing(DSP)systems.This paper introduces the design of the floating FFT based on VHDL language,Radix2 algorithm and 32 b single precision format are used in this project and the controller is modeled as a finite state machine.The whole design adopts Xilinx ISE 5.3 series software and advanced structured design mind and it is simulated and verified by ModelSim.The code coverage of all modules reaches 100 percent except few exceptional modules.Verification result shows that applying VHDL to FFT signal processing can accomplish floating FFT and the test work is very complete.This system can be expanded to 16 point or 32 point.
