  • Publication number: 20050228970
    Abstract: A processing system includes an arithmetic logic unit (ALU) sub-system that allows data associated with a prior instruction to be preserved for use with a next instruction or subsequent instruction without having to reload the value using an intermediate register. The ALU sub-system includes a pair of ALUs communicatively cross-coupled with a pair of accumulators. The processing system also includes a data selector coupled to the ALU sub-system for use with memory contention prediction. The data selector includes a constant generator that controls storage of data associated with a previous instruction in a bypass element, and a selector to choose between data from a databus element and data stored in the bypass element.

  • Publication number: 20050213661
    Abstract: A method, apparatus, computer medium, and other embodiments for motion estimation and compensation processing of video and image signals are described. Within a sequence of frames, block-based differences are taken between frames to exploit redundancies between pictures by taking a matchblock from the current picture and by determining a spatial offset in a corresponding reference picture which signifies a good prediction of where the current macroblock can be found. Multi-level motion estimation is performed in three stages to refine the resolution of the motion vector with reduced computational bandwidth. First, a matchblock from a reference frame is decomposed equally into several sub-matchblocks, each of which is searched in parallel over a search area decomposed into sub-blocks by a similar factor so as to determine a preliminary motion vector in the reference picture.

  • Publication number: 20050207663
    Abstract: The invention relates generally to compression of video data and specifically to lowering at least a cost of motion information while encoding a macroblock. According to one embodiment, the present invention searches for a matching block that lowers a cost of encoding the macroblock including the cost of encoding motion information. According to another embodiment, the present invention lowers the cost of encoding the macroblock including the cost of encoding motion information at one or more stages of a multiresolution search.

  • Publication number: 20050207488
    Abstract: A method, apparatus, computer medium, and other embodiments for discrete cosine transform and inverse discrete cosine transform (DCT/IDCT) of image signals are described. A DCT/IDCT module includes a plurality of different cores. One embodiment of a core includes two sets of lookup tables to provide multiplication and add operations for the DCT and IDCT functions. Another embodiment of a core include one set of lookup tables, while another embodiment of a core includes no lookup table. The DCT/IDCT module provides forward DCT and IDCT functionality without the use of additional multipliers.

  • Publication number: 20020113540
    Abstract: The present invention provides an electric shielding and anti-glaring multi-layer coating for cathode ray tube, and the method for making the same. A plurality of sputtering layers are formed on the outer surface of the glass panel of the CRT. An anti-glaring layer is formed on the outer surface of the sputtering layers by spraying. The plurality of sputtering layers contains conductive material such as ITO and having a protective layer to protect the conductive layer from acid corrosion. The multi-layer coating also has anti-reflection property in wide spectral range, and also has good hardness and resistance to fingerprint.
