    Abstract: Methods and apparatus for processing timedly-published data are provided. After receiving an operation request for the timedly-published data, at least one of an append-file and a delete-file can be written according to the operation request. The append-file corresponds to to-be-appended timedly-published data or post-updated timedly-published data. The delete-file corresponds to to-be-deleted timedly-published data or pre-updated timedly-published data. Each of the append-file and the delete-file uses a publishing time of the timedly-published data as an index.

    Abstract: A switch drive circuit capable of saving timers of fan processor is applied to a processor. The switch drive circuit includes multiple upper arm switch components, multiple lower arm switch components correspondingly electrically connected with the upper arm switch components, a first drive control unit and a second drive control unit. The upper arm switch components are driven by a first pulse width modulation signal and a second pulse width modulation signal. The first and second drive control units serve to receive a third pulse width modulation signal and a high-frequency pulse width modulation signal. The third pulse width modulation signal is switched between a high-level state and a low-level state to trigger and turn on the lower arm switch components.

  • Publication number: 20150134671
    Abstract: Methods and apparatus for data distribution and concurrence are provided. Data and a primary key of the data are obtained. A sub-key is assigned according to the primary key. The data are routed to a corresponding queue according to the sub-key. A writing operation is processed to the data in the queue. Because multiple sub-keys can exist under a same primary key and each sub-key can have one place for the writing operation, the writing operation can be processed simultaneously to the multiple sub-keys without affecting one another. The success rate of data writing concurrence can be improved and timeliness of the data can be ensured.

  • Patent number: 8693131
    Abstract: A system includes a self-servo-write (SSW) module, a read module, and a write module. The SSW module writes servo spirals on a magnetic medium of a hard disk drive (HDD) via a write head of the HDD. The read module reads the servo spirals via a read head of the HDD and generates read signals. The write module writes non-servo data on the magnetic medium via the write head based on the read signals before the SSW module writes servo wedges on the magnetic medium.
