Patent

CA 2267505

A moving pictures decompression device and method thereof which enable deterioration to be prevented regarding processing speed of a decode software when a moving pictures decompression is implemented. The moving pictures decompression device is provided with a CPU 1 in which a cache memory device is integrated, an internal memory device 2, a display device 3, an external storage device 4, and a decode software operating in accordance - with the CPU 1. A first measure which combines to be implemented a variable length code decoding, an inverse quantization, and an inverse DCT (Discrete Cosine Transformation) regarding a plurality of macro blocks, and a second measure which combines to be implemented a motion compensation processing regarding a plurality of macro blocks are provided. Thus it is capable of being prevented lowering of processing speed of a decode software when the moving pictures decompression is implemented.
