PURPOSE: To realize the moving image decoder for a storage system medium of a video rate at a low cost. CONSTITUTION: The decoder is made up of a variable length code decoding circuit 1, an inverse quantization circuit 2, an inverse discrete cosine transformation circuit 3, and an inter-frame motion compensation prediction generating circuit 4. A buffer memory 5 is arranged between the inverse quantization circuit 2 and the inverse discrete cosine transformation circuit 3 and a buffer memory 5 is used to realize a matrix transposition function required for inverse zigzag conversion processing and 2-dimension inverse DCT transformation. |
