  • Patent number: 6735611
    Abstract: The present disclosure provides an arithmetic processor comprising: an arithmetic logic unit having a plurality of arithmetic circuits each for performing a group of associated arithmetic operations, such as finite field operations, or modular integer operations. The arithmetic logic unit has an operand input data bus, for receiving operand data thereon and a result data output bus for returning the results of the arithmetic operations thereon. A register file is coupled to the operand data bus and the result data bus. The register file is shared by the plurality of arithmetic circuits. Further a controller is coupled to the ALU and the register file, the controller selecting one of the plurality of arithmetic circuits in response to a mode control signal requesting an arithmetic operation and for controlling data access between the register file and the ALU and whereby the register file is shared by the arithmetic circuits.

  • Patent number: 6728930
    Abstract: The present invention is directed to a method of updating a checksum associated with a packet of information to be transferred between correspondents. The method comprises the steps of: changing the value of a field; computing a complement; computing a difference; computing a one's complement difference from the first difference; computing a first intermediate checksum value equal to the sum of the complement of the checksum HC and the one's complement difference; computing a one's complement intermediate checksum from the intermediate checksum; computing a complement of the one's complement intermediate checksum; and replacing the checksum in the header with the updated checksum.

  • Patent number: 6714486
    Abstract: A system and method for producing and displaying chronological data according to user specified parameters. The system incorporates language, multi media, and animation into a time display device. The system can include typical features of a conventional time display device, such as an alarm function and a display face. The system also includes a translation engine for combining the parameters and a plurality of supplemental display data, including language, multi media, and animation data, to provide a translation template. The template helps to control the presentation of chronological data in a synchronized fashion by reformatting the chronological data into a translated display format, thereby providing to the user a personalized time display. The display includes selected images and/or language to represent the passage of numerical chronological data.

  • Patent number: 6711940
    Abstract: An indication of the elasticity of a non-Newtonian fluid is obtained by extending a fluid bridge between a pair of relatively movable surfaces that hold a fluid sample therebetween, and continuing a timewise progression of separation between two opposed moveable surfaces in a controlled manner until the displacing extension is great enough to cause a break point in the fluid sample. The extension of a fluid bridge at the break point is determined and used as an indication of elasticity.
