US Patent:

6625629, Sep 23, 2003

Filed:

May 23, 2000

Appl. No.:

09/577171

Inventors:

Guillermo Garcia - San Mateo CA

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 1710

US Classification:

708315, 708321

Abstract:

A system ( ) for signal processing using one or more filters includes a controller ( ) that partitions an impulse response of a filter into a plurality of impulse response blocks and calculates a Discrete Fourier Transform (DFT) of each impulse response block using a Fast Fourier Transform (FFT) algorithm. A processor ( ) that is coupled to the controller ( ) receives an input sample block including samples of a signal to be processed and receives the DFT of each impulse response block from the controller ( ). The processor ( ) calculates a DFT of the input sample block using an FFT algorithm, performs a spectral multiplication of the DFT of the input sample block with the DFT of each impulse response block, overlap-adds the blocks resulting from each spectral multiplication to create an output spectral block, performs an inverse FFT on the output spectral block to create an output sample block, and communicates the output sample block.
