<P>PROBLEM TO BE SOLVED: To reduce the amount of data to be transferred from an external memory, while limiting small mounting capacity of a cache memory when adopting a configuration where the cache memory is provided in addition to the external memory, when performing processing on an HD image size, or the like, of a large angle in a moving image decoding apparatus. <P>SOLUTION: In addition to a multi-frame memory (external memory) FrmMem for storing reference pixel data of a plurality of reference pictures, a cache memory CacheMem for storing the reference pictures is provided. A reference structure analyzer StrAna analyzes the reference structure of a picture. A reference picture controller FMCtr uses an analysis result of the picture reference structure to write a reference picture, having a high possibility of referring to a picture to be written the multi-frame memory FrmMem, as well as, to store the reference picture in the cache memory CacheMem. <P>COPYRIGHT: (C)2009,JPO&INPIT |
