  • Patent number: 5890281
    Abstract: A method and apparatus for attaching a set of components to a printed circuit board is presented. A second board includes the set of components to be attached to the printed circuit board. The second board attaches directly to the printed circuit board by attaching to pins of a through hole device, such as an application specific integrated circuit. The through hole device is mounted on one side of the printed circuit board. The through hole device comprises pins which protrude to the other side of the printed circuit board. The second board attaches to the protruding pins on the other side of the printed circuit board.

  • Patent number: 5507030
    Abstract: A program is translated by automatically generating a flowgraph, using the flowgraph to analyze the program to provide information about blocks of instructions in the flowgraph, and then using the flowgraph and the information about the blocks of instructions to generate translated instructions. Due to execution transfers to computed destination addresses that are not determined prior to program execution, it is not possible to include all of the program instructions in the flowgraph. Execution transfers to these computed destinations are coded as calls to an interpreter that interprets the untranslated code. Returns from the interpreter are made to block entry points. Moreover, information about the location of untranslated instructions in an original program is discovered during execution of a partial translation of the program, and that information is used later during re-translation of the original program.
