ABSTRACT:
To decrease costs in decoding a digital image signal. An image signal decoding apparatus stores forward reference frame data to be used for a decoding process in frame memories of a main memory provided in a common division, and also stores the frame data highly likely to be used for a motion compensation process in a motion compensation memory provided in a decoding processing division. Accordingly, it is possible, by sharing the main memory, to decrease manufacturing costs of the image signal decoding apparatus compared with the cases of providing dedicated frame memories for storing a current frame data and a forward reference frame data inside the decoding processing division respectively. In addition, it is possible to reduce power consumption during a decoding process compared with the cases of providing the dedicated frame memories.
