  • Patent number: 7992110
    Abstract: Structured ASIC circuitry that is intended to be functionally equivalent to a programmed block of FPGA circuitry (e.g., a programmed FPGA LUT) is verified for such functional equivalence by using the specification (logical or physical) for the structured ASIC circuitry as a starting point for an FPGA design project. If the design project results in the same FPGA circuitry as it was intended that the structured ASIC circuitry would be functionally equivalent to, the structured ASIC circuitry has been verified and can be added to one or more libraries of structured ASIC modules that are available for use in providing structured ASIC products that are functionally equivalent to programmed FPGA products.

  • Patent number: 7363596
    Abstract: A method is provided for creating and using a library of known logic elements for facilitating the design of equivalent FPGA, structured ASIC, or other integrated circuits. Each cell in the library corresponds to a circuit element and contains equivalent circuit models of the element for implementation in different integrated circuit technologies. The cells are named and indexed using a library cell key that contains a fixed set of cell properties which uniquely characterize the function of the cell. The cell key can be used to locate cells in the library or in circuit designs, and to verify that the circuit models contained in the cell implement the correct logic function.

  • Publication number: 20080019524
    Abstract: Provided are an apparatus and a method for a low power AES cryptographic circuit for an embedded system. The apparatus and method allows each round operation to be performed in an order of an add round operation, a sub byte operation, a shift row operation, and a mix column operation in order to realize a small circuit area by making maximum reuse of designed element modules. When data is input, on the first place, operations are repeated in the above order from a first round to a round right before a last round. During a last round, only an add round key operation and a sub byte operation, and a shift row operation are performed, and then an add round key operation using a secret key is performed. At this point, each operation is performed on data by a 8-bit unit.

  • Publication number: 20070280354
    Abstract: In one embodiment of a method of decoding a first frame sequence layer, at least one motion vector of an image block in a frame of the first frame sequence layer is determined based on scaling a motion vector for an image block in a frame of a second frame sequence layer. The motion vector for the image block in the frame of the second frame sequence layer is scaled based on a display size difference between frames in the second frame sequence layer and frames in the first frame sequence layer. A display size of frames in the second frame sequence layer is different than a display size of frames in the first frame sequence layer, and the second frame sequence layer does not include a frame temporally coincident with the frame of the first frame sequence layer. The image block in the frame of the first frame sequence layer is decoded based on the determined motion vector.
