Patent ID: 8229002

Claim:
A method of decoding a digital video data stream in a digital video decoding system, comprising: (a) configuring an inverse quantization accelerator and an inverse transform accelerator to respectively perform an inverse quantization function and an inverse transform function on a first set of data elements of the data stream, the first set of data elements being of a first media format; (b) performing inverse quantization on an i th data element of the first set of data elements; (c) performing an inverse transform operation on a product of the inverse quantization of the i th data element, while performing inverse quantization on an i+1 st data element in the first set of data elements; (d) configuring the inverse quantization accelerator and an inverse transform accelerator to respectively perform an inverse quantization function and an inverse transform function on a second set of data elements of the data stream, the second set of data elements being of a second media format; (e) performing inverse quantization on a j th data element of the second set of data elements with the inverse quantization accelerator; and (f) performing an inverse transform operation on a product of the inverse quantization of the j th data element, while performing inverse quantization on a j+1 st data element of the second set of data elements.
