  • Patent number: 7768520
    Abstract: In a video application, a method and system provide different sizes of data-fetch where the data transfer rate between a decoder and an external memory (e.g., DDR memory) is extremely high, as for example in HDTV systems. The invention in one form divides a reference frame into different tiles where each tile is hierarchically divided into smaller tiles to a level where the minimum tile size is the same as the fixed burst size of the DDR memory. The method also provides for arranging the biggest tiles into different banks and pages so that even if the block to be fetched falls across tile boundaries, the latency penalty in the tile transition will be minimized. The invention provides advantages also for progressive and interlaced data fetch.

  • Patent number: 7764837
    Abstract: A technique for continuously recognizing a character entry into a computer. In one example embodiment, this is achieved by drawing a character in a continuous stroke order using a stylus [210] on touch screen [220]. As associated data of the drawn continuous stroke order is then inputted into a continuous character recognizer [930] via the touch screen [220]. One or more hypothesis candidate characters including the continuous stroke order are then produced by the continuous character recognizer [930] upon a partial recognition.
