| Abstract: | This paper investigates and implements the Bruun FFT algorithms on complex,real,and real - symmetric data. The paper analyzes and evaluates the arithmetics and the characteristics of the Bruun algorithms .and presents their implementation structures and methods. The execution time of the implemented algorithms on the TMS320C30 is given. They are 35% faster than the radix - 2 FFT. |
