Information processor and information processing method

An information processing method comprising:

• a program obtaining step of obtaining a program;
• a program storage step of storing the program obtained in the program obtaining step in any of plural storage areas;
• a program execution step of executing the program;
• a memory information storage step of storing execution memory information indicating a storage area which contains a program to be executed in the program execution step, compression information indicating compression states of programs stored in the storage areas, and memory relationship information indicating a relation of the plural storage areas;
• a program execution area switching step of selecting one of the storage areas on the basis of the execution memory information;
• a program storage area switching step of selecting one of the storage areas on the basis of the information stored in the memory information storage step;
• a program writing step of writing the program;
• a program compression step of compressing the program;
• a program restoration step of restoring the program compressed in the program compression step;
• and
• a memory information updating step of updating the information stored in the memory information storage step.

A computer-readable storage medium which contains a program for making a computer implement:

• a program obtaining process for obtaining a program;
• a program storage process for storing the program obtained in the program obtaining process in any of plural storage areas;
• a program execution process for executing the program;
• a memory information storage process for storing execution memory information indicating a storage area which contains a program to be executed in the program execution process, compression information indicating compression states of programs stored in the storage areas, and memory relation information indicating a relation of the plural storage areas;
• a program execution area switching process for selecting one of the storage areas on the basis of the execution memory information;
• a storage area switching process for selecting one of the storage areas on the basis of the information stored in the memory information storage process;
• a program writing process for writing the program;
• a program compression process for compressing the program;
• a program restoration process for restoring the program compressed in the program compression process;
• and
• a memory information updating process for updating the information stored in the memory information storage process.
