More Information
Summary:A data processing system including at least one storage device for storing and retrieving data and connected to a storage device interface that controls the storing and retrieving of data from the storage device and further includes a data buffer for storing data retrieved from or being stored in the storage device. The data processing system includes a storage device driver that receives storage access commands from a processor, provides commands to the interface in response to these commands to the access commands from the processor and also provides commands for data not requested by the processor. The commands for data not requested by the processor provide for the temporary storage of data in the storage device interface data buffer. This data not requested by the processor is retrieved in anticipation of commands to be sent by the processor. The storage driver manages this buffer to optimise the amount of storage dedicated to the storage of data for these anticipatory commands.
