Koji Takatomi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8078423
    Abstract: A computer terminal retrieves pin data related to respective pins of a plurality of Field Programmable Gate Array that are mounted on a board. The computer terminal retrieves setting data related to a connection check. Upon retrieving the pin data and the setting data, the computer terminal assigns, as data for the connection check to all the pins that can output data, unique data that is unique to each pin. The computer terminal generates input pin data and output pin data containing the unique data, stores therein the input pin data and the output pin data, and generates checking circuits that check connections between output pins and input pins. The computer terminal generates checking data based on the checking circuits.

  • Patent number: 7761822
    Abstract: A method and apparatus for generating file information including setting clock information regarding a clock condition and a clock speed to be used by a speed conversion circuit block, reconstructing the clock circuit block including a new clock for accommodating insertion of the speed conversion circuit block, and associating connection terminal information indicating a connection relationship of connection terminals with speed conversion object information having set, as a speed conversion object, a connection terminal requiring connection speed conversion.

  • Patent number: 7735028
    Abstract: A computer is allowed to execute an information acquisition process that acquires a file expressing information on pins used in respective ports provided in each block of a logic circuit to be redesigned and information indicating connection relationships between the ports (#2); execute a multiplexer disposition process that, based on the file, classifies pins of output ports of a block into a number of pin groups that is less than the number of pins, and disposes a multiplexer having a function to multiplex a signal output from each pin classified in the same pin group (#11, #13); and execute a demultiplexer disposition process that, based on that file, disposes a demultiplexer having a function to demultiplex signals that have been output from output ports of a block and multiplexed by the multiplexer, and a function to output each demultiplexed signal to input ports of respective input destination blocks (#12, #13).
