| 20090110077 | IMAGE CODING DEVICE, IMAGE CODING METHOD, AND IMAGE CODING INTEGRATED CIRCUIT - When compression encoding processing of an image is performed in units of macroblocks using pipeline structure, application of the skip mode or the like according to MPEG4AVC to compression encode an encoding target block requires motion vectors and the like of adjacent blocks of the encoding target block. However, depending on the structure of the pipeline stages, the motion vectors and the like may not be determined. In such cases, the skip mode cannot be applied to compression encode the encoding target block. The present invention aims to solve this problem and (i) calculates all motion information candidates, of the encoding target block, corresponding to all motion information selectable by a previous block of the encoding target block, and (ii) selects, as the motion information of the encoding target block in the skip mode, the motion information corresponding to the motion information determined for the previous block. | 04-30-2009 |

| 20110122952 | MOTION ESTIMATION DEVICE - A motion estimation device configured to estimate motion for blocks included in an input picture using a reference picture includes an internal reference memory configured to store the reference picture transferred from outside the motion estimation device; a motion estimator configured to estimate motion information for a target block that is a block of the input picture and where motion is to be estimated, using pixel data of the reference picture stored in the internal reference memory; a motion compensator configured to perform motion compensation for the target block using the motion information estimated by the motion estimator; and a reference memory manager configured to control the internal reference memory. The reference memory manager is configured to control the internal reference memory to store a luminance reference picture and a color-difference reference picture as the reference picture. | 05-26-2011 |
| 20110161622 | MEMORY ACCESS CONTROL DEVICE, INTEGRATED CIRCUIT, MEMORY ACCESS CONTROL METHOD, AND DATA PROCESSING DEVICE - A memory access control unit is provided with a storage unit for storing a page table that stores a correspondence between a piece of data, a virtual page number, and a physical page number for all pages, and a conversion unit that includes a buffer for storing, for each of a subset of the pages, the virtual page number and the physical page number in correspondence, and a conversion processing unit operable to convert a virtual address into a physical address in accordance with content stored in the buffer. When the virtual page number of the virtual address included in the access request does not exist in the buffer, the conversion processing unit overwrites, in the buffer, (i) the virtual page number and the physical page number of a page for which a completed conversion count, indicating a number of times the virtual address of the page has been converted to the physical address, has reached a planned conversion count, with (ii) the virtual page number of the virtual address included in the access request and the physical page number corresponding, in the storage unit, to the virtual page number. | 06-30-2011 |
