16 point DIF FFT using radix 4 fftAbstract: 16 point DIF FFT using radix 2 fft , EMAIL: dsp.support@analog.com Choosing and Using FFTs for ADSP21xx Last Modified: 06/18/96 FFT is , the advanced addressing mechanism, the ADSP21xx can process the radix4 FFT significant faster than , between the floating point FFT and fixed point FFT implementations. At each calculation stage of fixed , large FFTs. Using of FFTs on ADSP21xx The output of FFT processing is the complex DFT X(k) of the , the results The FFT result can be checked by plotting the result in the ADSP21xx simulator data
