Abstract
A process for decoding MPEG encoded image data stored in a system memory utilizing a configurable image decoding apparatus. The process comprises the steps of: (a) extracting macroblock information from said MPEG encoded image data, the macroblocks containing image data and motion compensation data; (b) extracting a series of parameters from the MPEG encoded image data for decoding the MPEG encoded data; (c) determining quantization factors from the encoded image data; (d) configuring the configurable image decoding apparatus, including (i) configuring a means for parsing the macroblock data into motion vectors and image data with the series of parameters with the parameters for decoding the encoded data; (ii) configuring a means for performing inverse quantization with the quantization co-efficients; (e) determining a decoding order of the extracted macroblock information to be decoded; (f) providing said extracted macroblock information to the parsing means in the decoding order; (g) combining decoded image data with motion vectors extracted by the parsing means; and (h) storing the combined data in the system memory.
