  • Patent number: 8238822
    Abstract: The present invention relates to a method for selecting an installation position of a link antenna of an in-building RF repeater, a cable device thereof, and a terminal. The method selects the position for measuring the greatest Ec/Io by using directivity of the link antenna in an area for installing the link antenna. The link antenna is installed at the selected position. The direction with the greatest Ec/Io that is measured by using directivity of the link antenna is fixed to be a desired direction from among target directions to be directed by the link antenna. In this instance, measurement of Ec/Io by using directivity of the link antenna is performed by a mobile station connected to the link antenna through an access cable. Accordingly, the link antenna can be installed at the optimized position and in the optimized direction. Hence, the Ec/Io within the building is substantially reduced.

  • Patent number: 7926046
    Abstract: This invention describes a compilation method of extracting and implementing an accelerator control program from an application source code in a processor based system. The application source code comprises arrays and loops. The input application source code is sequential, with loop, branch and call control structures, while the generated output of this invention has parallel execution semantics. The compilation method comprises the step of performing loop nest analysis, transformations and backend processes. The step of loop nest analysis consists of dependence analysis and pointer analysis. Dependence analysis determines the conflicts between the various references to arrays in the loop, and pointer analysis determines if two pointer references in a loop are in conflict. Transformations convert the loops from their original sequential execution semantics to parallel execution semantics. The back-end process determines the parameters and memory map of the accelerator and the hardware dependent software.
