PIPELINE FFT ARCHITECTURE AND METHOD

PIPELINE FFT ARCHITECTURE AND METHOD

Techniques for performing Fast Fourier Transforms (FFT) are described. In some aspects, calculating the Fast Fourier Transform is achieved with an apparatus having a memory ( 610 ), a Fast Fourier Transform engine (FFTe) having one or more registers ( 650 ) and a delayless pipeline ( 630 ), the FFTe...

Zusammenfassung:Techniques for performing Fast Fourier Transforms (FFT) are described. In some aspects, calculating the Fast Fourier Transform is achieved with an apparatus having a memory ( 610 ), a Fast Fourier Transform engine (FFTe) having one or more registers ( 650 ) and a delayless pipeline ( 630 ), the FFTe configured to receive a multi-point input from the main memory ( 610 ), store the received input in at least one of the one or more registers ( 650 ), and compute either or both of a Fast Fourier Transform (FFT) and an Inverse Fast Fourier Transform (IFFT) on the input using the delayless pipeline.
