Patent ID: 7437394

Claim:
A method for split processing input data having first and second half data into first and second split discrete cosine transformed data, a discrete cosine whole transform defining first and second radix-2 discrete cosine transforms, the whole discrete cosine transform and the first and second radix-2 discrete cosine transforms are fast discrete cosine transforms, the method comprising the steps of, whole discrete cosine transforming the input data into merged discrete cosine transformed data, the merged discrete cosine transformed data equaling the whole discrete cosine transform of the input data, split combinational processing the merged discrete cosine transformed data into first and second split discrete cosine transformed data, the first and second split discrete cosine transformed data respectively equaling the first and second radix-2 discrete cosine transforms of the first and second half data, and communicating the first and second split discrete cosine transformed data over a communication link to a storage device.
