| Title of Invention | APPARATUS AND METHOD FOR ENCODING AND COMPUTING A DISCRETE COSINE TRANSFORM USING A BUTTERFLY PROCESSOR |
|---|---|
| Abstract | An apparatus to detennine a transfonn of a block of encoded data the block of encoded data comprising a plurality of data elements. An input register is configured to receive a predetennined quantity of data elements. At least one butterfly processor is coupled to the input register and is configured to perfonn at least one mathematical operation on selected pairs of data elements to produce an output of processed data elements. At least one intennediate register to coupled to the butterfly processor and configured to temporarily store the processed data. A feedback loop is coupled to the intennediate register and the butterfly processor, and where if enabled, is configured to transfer a first portion of processed data elements to the appropriate butterfly processor to perfonn additional mathematical operations and where if disabled, is configured to transfer a second portion of processed data elements to at least one holding register. |
