A data processing system including a storage section, a processing section, a control section, and a memory. The control section performing an action to allocate, to all of the ports, a time slot of a period of time which guarantees one seek action within a cycle time period which is the shortest time period within which it is permitted for the ports to successively accept a readout instruction, allocate, when another readout instruction is received, two or more time slots to that one of the ports which is designated by the readout instruction within a first cycle time period, and allocate one time slot to the port designated by the readout instruction within a second cycle time period after the first cycle time period. The processing section being operable to read out data from the storage section within one cluster per one time slot through that one of the plural ports to which the time slot is allocated by the control section and write the read out data into the memory and then process or output the data read out from the memory.
