  • Publication number: 20070300202
    Abstract: A standard cell, placed between a power rail and a ground rail in an integrated circuit, has active areas with connecting arms that extend beneath the power rail and ground rail. The connecting arms conduct current between the power and ground rails and the source regions of transistors in the active areas. The connecting arms include segments extending from these source regions to points beneath the power and ground rails, and segments running longitudinally beneath the power and ground rails. The connecting arms replace metal wiring that would otherwise be required, enabling the size of the standard cell to be reduced.

    Abstract: A computer-readable recording medium storing a data collection program for easily performing a process to collect data from a plurality of core systems at desired timing, and combine and analyze the data and data in a local database. An access request decomposer determines at least one remote database to be accessed, based on an access request accepted by an information management unit, and decomposes the access request into remote access requests each for accessing each of the remote databases. An access unit accesses the remote databases based on the remote access requests created by the access decomposer and extracts data from the remote databases. An aggregation unit aggregates the data extracted by the access unit, and then the aggregation result is displayed.

  • Publication number: 20060056439
    Abstract: A method and apparatus enable high speed transfer of real-time AV data over a bus. When transmitting real-time data of a specific format using isochronous packets, data indicating the transfer rate is added to the isochronous packet. The playback speed can be changed and playback can be stopped while maintaining the transfer rate. High speed data transmission is thus possible.

  • Patent number: 6690879
    Abstract: Apparatus is adapted for recording and reproducing compressed video data in a selected one of two recording formats, of which a first format is for recording the compressed video data in N (N≧3, and representing an integer) number of tracks on a magnetic tape by dividing the video data into N number of groups, and a second format is for recording data, as auxiliary data independent from the compressed video data, in two of the tracks at both ends, and the compressed video data in (N−2) number of the tracks. In the second recording format, the recording is carried out by setting a data length of an error correction code for sync blocks longer than a data length of another error correction code for sync blocks in the first recording format.
