  • Method and apparatus for extracting short runs of ambiguity from finite state transducers
    Publication number: 20020152062
    Abstract: A method extracts all “short” ambiguity from an input FST (i.e., ambiguities of one arc in length). The method factors the input FST into a first factor and a second factor such that the second factor contains all ambiguity that is one arc long, and the first factor contains all other parts of the input FST. The method a priori prevents the creation of some redundant intermediate symbols.

  • Graphics processing apparatus and graphics processing method
    Patent number: 6466229
    Abstract: Disclosed is a graphics processing apparatus capable of drawing graphics at high speed with a small memory capacity even in the case of drawing graphics in which a drawing element and a clip element exist mixedly or which has many overlaps. A drawing command is interpreted by a command interpretation unit and data is converted to linear vectors by a vector data generation unit. A display list generation unit generates a display list. With respect to graphics in which a clip element and a drawing element exist mixedly, display lists of both elements are merged and a clipping process is performed at the level of the display lists while executing predetermined determination. In the case of graphics having many overlaps, the overlaps are similarly removed at the level of the display lists. A display list drawing unit has a processing unit of 2N and performs drawing while executing a DDA operation in parallel.
