Summary:To highly accurately predict data to be accessed by a processing circuit in the future.SOLUTION: A management device 18 manages accesses to a plurality of kinds of storage units 14 by a processing circuit 12. The storage unit 14 includes a plurality of first regions, and the first region includes a plurality of second regions. The management device 18 includes a management unit (management information storage unit 30)and a prediction unit 26. The management unit (management information storage unit 30) manages a management table 31. The management table 31 is a table associating identification information of the first region with access management information specifying access information indicating whether or not the processing circuit 12 has already accessed the second region for each of the plurality of second regions included in the first region. The prediction unit 26 predicts the second region to be accessed by the processing circuit 12 in the future on the basis of the access management information.SELECTED DRAWING: Figure 1 【課題】処理回路が将来アクセスするデータを高精度に予測する。【解決手段】管理装置18は、処理回路12による複数種類の記憶部14に対するアクセスを管理する。記憶部14は、複数の第1領域を含み、第1領域は、複数の第2領域を含む。管理装置18は、管理部(管理情報記憶部30)と、予測部26と、を備える。管理部(管理情報記憶部30)は、管理テーブル31を管理する。管理テーブル31は、第1領域の識別情報と、第1領域に含まれる複数の第2領域の各々ごとに、第2領域が処理回路12によってアクセス済であるか否かを示すアクセス情報を規定したアクセス管理情報と、を対応付けたテーブルである。予測部26は、アクセス管理情報に基づいて、処理回路12が将来アクセスする第2領域を予測する。【選択図】図1
