Simulation of Digital Signal Processor-FFT for Communication System Applications
Prasad Kulkarni, Balaji G. Hogade, Vidula Kulkarni · 2016
The Fast Fourier Transformation (FFT) is widely used in communication systems applications. The FFT operation is performed by Digital signal processor (DSP). This paper presents the architecture of Digital signal processors designed using VHDL to compute the FFT suitable for communication applications. The processor has 32 bit address and data bus, on chip dual Port RAM, ROM and serial transceiver. The processor has special instruction set i.e. Special Instruction, Harvard architecture which computes the radix -2, 8 Point FFT in 39.3ns.
