  • Publication number: 20090148057
    Abstract: An embodiment of a method for encoding a source image comprising multiple data units, performed by an image encoding unit, comprises the following steps. A quantized DC coefficient and multiple AC coefficients of a data unit are generated. A value at the (0,0) element of the first data unit is determined according to the quantized DC coefficient. A variable length coding (VLC) stream of the data unit is generated by encoding the determined value and the AC coefficients. An encoded bitstream comprising a restart mark followed by the VLC stream of the data unit is generated. An offset pointing to the beginning of the restart mark of the encoded bitstream is stored in a random access table. A compression image comprising the encoded bitstream and the random access table is generated.

  • Publication number: 20090058864
    Abstract: A graphics processing system is provided. The graphics processing system comprises a display unit, a frame buffer, an interface, and a controller. The frame buffer, defined by an initial pointer and a boundary pointer first image data in the frame buffer, stores first image data corresponding to a first image area displayed on the display unit. The interface receives a scrolling request directing the first image to scroll in a vertical and/or horizontal direction. The controller determines a reading pointer of the frame buffer according to the initial and boundary pointers and the scrolling request, loads new image data into a memory location at which a particular part of the first image data is stored.

  • Patent number: 7065421
    Abstract: A manufacturing management system and method. The system includes a monitor module and a planning module. The monitor module receives real-time yield information of one product currently being processed in a production line. The planning module dynamically manages a manufacturing schedule of the product by holding lots corresponding to the product to avoid being processed if the yield information is greater than a target yield, and releasing additional lots corresponding to the product to be processed by the production line if the yield information is less than the target yield.

  • Patent number: 6871110
    Abstract: A method and system is provided for dynamically coordinating one or more product orders with product parts progressing through a manufacturing process flow. After identifying a first order for generating one or more lots of parts for manufacturing a first product, wherein the first order identifies a predetermined base feature, one or more customer specific features, one or more order specific features, and the quantity of the first product, A smart code is assigned to the first order and the lots of parts, wherein the smart code identifies an association between the first order and the lots of parts. An analysis is then performed, based on the smart codes assigned thereto, to see whether one or more available lots of parts of a second order in production are ready to be converted to produce the first product. The smart code of the available lots is changed to the smart code of the first order if the available lots of the second order are chosen to be further processed for fulfilling the first order.
