    摘要: A method of automatically configuring an autoconfigurable computer peripheral device as a primary device or as a secondary device. There are four possible cases: (1) no other device present, (2) legacy primary device present, (3) legacy secondary device present and (4) second autoconfigurable device present. Host computer device configuration application software provides a signal or numerical data indicating a bit position within an identification number within each autoconfigurable device. If a device identification has a particular logical value at the bit position, the device responds to the signal from the computer. If the device identification has a different particular logical value at the bit position, the device determines whether another device is responding to the signal from the computer. If a first device determines that it should not respond, and a second device responds, the first device provisionally configures itself as a secondary device. If all bit positions are exhausted, and a device has not provisionally configured itself as a secondary device, then the device provisionally configures itself as a primary device. The host computer then sends a particular numerical value to the devices. Depending on the particular numerical value, each device configures itself to its provisional configuration, or to the opposite configuration from its provisional configuration, or unconfigures itself.

    摘要: The present invention discloses a method and system for providing defect management of a bulk data storage media wherein logical addresses of media data blocks are continuously slipped to omit all media data blocks determined to be defective at the time of an initial media format. Thereafter, selectable parameters are utilized to define a logical zone including both a user data area and corresponding replacement data area on the media such that proper selection of the parameters provides defect management optimized for a particular use of the media.

    摘要: A method of automatically configuring a computer peripheral device as a primary device or as a secondary device. There are four possible cases: (1) no other device present, (2) legacy primary device present, (3) legacy secondary device present and (4) second unconfigured device present. Each unconfigured device determines whether there are any legacy devices already installed and whether there is another unconfigured device installed without requiring any changes to the host operating system software. Unconfigured devices assert a signal after reset with a first timing that is dependent on an electronically readable identification on the device. For case (4), the first device to detect the signal becomes the secondary device. In case of a tie, unconfigured devices continue to assert the signal with a second timing that is dependent on the electronically readable identification on the device. A device that detects the signal being present at the end of the second timing configures itself as a secondary device. A device that does not detect the signal being present at the end of the second timing configures itself as a primary device.

    摘要: A method of formatting rewritable compact optical disks. In some example embodiments, a disk is initially partially formatted for immediate useability, and then additional incremental formatting is provided until the disk is completely formatted. The additional formatting may take place while a drive is off-line. In one embodiment, data is written to an unformatted disk with data writing and formatting taking place simultaneously. In various example embodiments, lead-in and lead-out areas may be written first with nothing in between or lead-in and lead-out areas may optionally written only if needed.

    摘要: A method and system for sampling on the fly one or more integrated circuit nodes coupled to one or more bus domain clocks of an integrated circuit using minimal clock cycle delay synchronization. Sample on the fly circuitry, set-reset circuitry and metastable rejection circuitry are used to provide a sufficient pulse width for sampling on the fly the one or more nodes when the one or more bus domain clocks require asynchronous operation. The sample on the fly circuitry is also operable to synchronously sample on the fly the one or more nodes.
