One of the areas that major demands of application specific circuits design is digital signal processing (DSP). Fast Fourier Transform is a computationally intensive DSP function, widely used in many applications

radix-2 and radix-4 algorithms have been used mostly for practical applications due to their simple structures

Here we use radix-2 Fast Fourier Transform architecture design, under the point of view of its reusability to be embedded in different applications.

Here Radix-2 FFT design has been modeled in VHDL VHDL code is developed which is portable among different synthesis tools

and technologies. After this the system is simulated and synthesized with the Quartus II from

Altera for evaluation performance purposes

Software Tools

Modelsim from Menter Graphics : Logic simulation tool for verification and debugging of digital circuits in VHDL.
