ABSTRACT:
A decoder and decoding method is disclosed for real time decompression of coded picture-, video- and film information. The decoder provides an efficient implementation of the functions requiring an optimized processor comprising one multiplier having a minimized chip area. The process of decoding, frame reconstruction, block to raster conversion and color space conversion are combined using concurrent processing and resource sharing techniques. The processes IQ, IDCT, FR and optional CSC use one specialized processor comprising only one multiplier and further elements having no multiplier. The processor comprises process controls which are independent of each other for controlling the decompression.
