PROBLEM TO BE SOLVED: To reduce the probability of delay in memory access by a specific task.SOLUTION: An information processing device comprises: a memory that includes a plurality of areas; a task execution unit that executes a plurality of tasks; a storage unit that stores authority information indicating the authority of access to an area by a task; and an access management unit that when the task has accessed the area, if the authority information indicating the authority of access to the area by the task is stored in the storage unit, determines the authority of access on the basis of the authority information, and if the authority information is not stored, stores the authority information indicating the authority of access to the area by the task in the storage unit. The access management unit, when storing authority information on a first task in the storage unit, out of authority information on the first task and authority information on a second task allowed to be delayed in execution more than the first task, preferentially overwrites the authority information on the second task. |
