    摘要: Systems and methods of selective data mirroring are disclosed. In a particular embodiment, a device is disclosed that includes a data storage medium and a controller operably coupled to the data storage medium. The controller configured to selectively enable a data mirroring function to copy data in a first data storage location of the data storage medium to one or more second data storage locations of the data storage medium when the one or more second data storage locations do not have valid primary data stored to them.

    摘要: In a processor-based system, priorities are established among a plurality of interrupt sources by grouping the interrupt sources in accordance with an operating condition of the system. The assignment of the interrupt sources into groups is accomplished through programmable registers which associate flag locations in an interrupt status register with flag locations in a group status register. The operating condition upon which the grouping of interrupt sources is based may be the handling of a particular interrupt, based upon which a next expected interrupt source is assigned to a high priority group.

    摘要: Methods and control systems for delaying a seek once a command is received to further load a buffer with read look ahead data are described. The methods involve calculating when or at what point the prefetching should cease and a seek should be initiated so that the actuator arm arrives at a new track just in time to begin reading the target data. The control systems include a processor that instructs a servo control to hold the actuator on a track while data is prefetched and loaded into a buffer until a seek must be initiated to allow the actuator to arrive at the new track just in time to begin reading the new target data.
