Preload controller, preload control method for controlling preload of data by processor to temporary memory, and program
A preload controller for controlling a bus access device that reads out data from a main memory via a bus and transfers the readout data to a temporary memory, including a first acquiring device to acquire access hint information which represents a data access interval to the main memory, a second acquiring device to acquire system information which represents a transfer delay time in transfer of data via the bus by the bus access device, a determining device to determine a preload unit count based on the data access interval represented by the access hint information and the transfer delay time represented by the system information, and a management device to instruct the bus access device to read out data for the preload unit count from the main memory and to transfer the readout data to the temporary memory ahead of a data access of the data.
