  • Publication number: 20030212729
    Abstract: Modular multiplication of two elements X(t) and Y(t), over GF(2), where m is a field degree, may utilize field degree to determine, at least in part, the number of iterations. An extra shift operation may be employed when the number of iterations is reduced. Modular multiplication of two elements X(t) and Y(t), over GF(2), may include a shared reduction circuit utilized during multiplication and reduction. In addition, a modular multiplication of binary polynomials X(t) and Y(t), over GF(2), may utilize the Karatsuba algorithm, e.g., by recursively splitting up a multiplication into smaller operands determined according to the Karatsuba algorithm.

  • Patent number: 6633242
    Abstract: The present invention provides an entropy coding scheme using an adaptable prefix code. The prefix code is a binary representation of the algorithm used to compress and decompress the data. There are prefix zeros that represent the number of significant binary digits that follow the first one. According to one embodiment, this scheme works on both positive and negative integers and encodes lower order integers with a smaller length of codeword. In another embodiment, the zero integer is encoded as a special case with the shortest codeword. In yet another embodiment, the present scheme is preferred by data sets that are clustered about zero, such as image data sets that have been transformed via a wavelet transform or a discrete cosine transform.

  • Patent number: 5586910
    Abstract: A rear clamping nut retaining feature for a hardline connector includes a rear nut having a compression ring retained therein in such a manner that the compression ring is able to move axially within the rear nut. The inner peripheral surface of the nut has an axially extending protrusion which when the compression ring is forced into an opening in the rear nut the protrusion deforms radially inward into a slot located on the outer peripheral surface of the compression ring thus holds it in place. The size of the protrusion and the size of the slot are related such that the volume of the protrusion is less than the volume of the groove to thereby allow the desired axial movement of the rear nut and compression ring.

  • Patent number: 5381519
    Abstract: Primitive data in the form of defined lines for a computer graphics display is processed as by interpolating triangles, as during scan conversion, and by treating lines as triangle edges. An offset point is selected, e.g. offset perpendicularly from the line midpoint a distance of one-half the line length to define a triangle vertex along with the line endpoints. The resulting triangle is interpolated for example as with barycentric coordinates. Accordingly, the line may be interpolated, e.g. shaded, as though it were an edge of the defined triangle. For lines, sample points are coerced to lie on the triangle edge.

  • Patent number: 5361386
    Abstract: Barycentric coordinates are determined using data readily available in computer graphics systems and defining polygons in world space so as to interpolate such polygons with regard to pixels selected by scan conversion. The barycentric coordinates are employed to interpolate the polygons, for example to accomplish smooth shading or texture mapping. The process of the system involves defining primitive data (e.g. polygons) in a space not subject to nonlinear distortion (e.g. world space), transforming select primitive data to a space that is subject to nonlinear distortion, calculating in the space subject to nonlinear distortion (e.g. screen space) a set of areas (e.g. pixels) within a defined primitive (e.g.

  • Patent number: 4918626
    Abstract: Image data is composed from primitives (polygons) to attain data for displays with the removal of hidden surfaces and smooth-appearing edges. Defined polygons are tested for priority in a determined field of vision by scan conversion to specify individual picture elements (pixels). Polygon contention for pixels is resolved by determining the edge of intersection between the planes of such polygons and testing the signs of certain values in accordance with predetermined criteria. Subpixel priority is treated for similar resolution to provide improved antialiased images.
