More Information
Summary:A data processing system including at least one storage device for storing and retrieving data from several rotating tracks where each track includes sequentially located blocks for the storage of data. A storage interface is connected for controlling this storage device. The storage interface includes a data buffer for storing data retrieved from the storage device. A storage driver receives storage access commands from a processor to provide commands to the interface. This storage driver further includes the capability to provide commands for the transfer of data that has not been requested by the processor to the data buffer. These commands for data not requested by the processor call for data stored in sequence after data in storage devices read in response to read commands from the processor.
