Abstract
A method and apparatus for compression/decompression and filtering of a signal in which the apparatus has an input register ( ) which receives the received signal, an output register ( ) which transmits a processed signal and a distributed arithmetic processor ( ) having a plurality of operational modes. The distributed arithmetic processor is coupled to the input register by an input path and is coupled to the output register by an output path. The apparatus also has a DCT butterfly processor ( ) selectively switched into the input path in response to selection of a predetermined operational mode from the plurality of operational modes. An IDCT butterfly processor ( ) is also selectively switched into the output path in response to the selection of one of the predetermined operational modes. Additionally, the apparatus selectively functions as a FIR filter with both the DCT butterfly processor ( ) and IDCT butterfly processor ( ) removed from the input and output paths.
