<p><P>PROBLEM TO BE SOLVED: To provide an information processing technology for achieving speed-up of processing while suppressing a scale of a primary storage device. <P>SOLUTION: An information processing apparatus performs the processing of input data by sequential use of a plurality of pieces of reference data. The information processor includes: a secondary storage part 101 holding the plurality of pieces of the reference data; a primary storage part 102 accessible at higher speed than the secondary storage part; a reading part 103 reading the reference data used for the processing to the primary storage part from the secondary storage part; an execution part 104 performing the processing of the input data by use of the reference data read to the primary storage part; and a decision part 105 deciding whether to pre-read the reference data of a schedule based on at least either of probability that the reference data scheduled to be used by the execution part is changed and a data amount of the scheduled reference data. The reading part pre-reads the reference data of the schedule when it is decided by the decision part that the reference data of the schedule are preread, and does not preread the reference data of the schedule when it is decided by the decision part that they are not preread. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
