Abstract
A disclosed information processing method is executed by a computer and includes: storing context representing a state of a processor in the computer into a certain area of plural areas included in a memory of the computer, wherein same data is stored in each of the plural areas by memory mirroring; performing a setting to switch a type of the certain area from a type of an area for which the memory mirroring is performed to a type of an area for securing data; and upon detecting that reset of the computer was performed, recovering, by using the computer, the state of the processor by using data stored in the certain area.
Claims8
An information processing method, comprising:
- storing, by using a computer, context representing a state of a processor in the computer into a certain memory area of a plurality of memory areas included in a memory of the computer, wherein same data is stored in each of the plurality of memory areas by mirroring;
- performing, by using the computer, a setting to switch a type of the certain memory area from a type of a memory area for which the mirroring is performed to a type of a memory area for securing data;
- and
- upon detecting that reset of the computer was performed, recovering, by using the computer, the state of the processor by using data stored in the certain memory area.
An information processing apparatus, comprising:
- a memory having a plurality of memory areas each of which stores same data by mirroring;
- a processor;
- a first processing unit that stores context representing a state of the processor into a certain memory area of the plurality of memory areas;
- and
- a second processing unit that performs a setting to switch a type of the certain memory area from a type of a memory area for which the mirroring is performed to a type of a memory area for securing data, and
- wherein, upon detecting that reset of the information processing apparatus was performed, the first processing unit recovers the state of the processor by using data stored in the certain memory area.
A computer-readable, non-transitory storage medium storing a program for causing a computer to execute a process, the process comprising:
- storing context representing a state of a processor in the computer into a certain memory area of a plurality of memory areas included in a memory of the computer, wherein same data is stored in each of the plurality of memory areas by mirroring;
- performing a setting to switch a type of the certain memory area from a type of a memory area for which the mirroring is performed to a type of a memory area for securing data;
- and
- upon detecting that reset of the computer was performed, recovering the state of the processor by using data stored in the certain memory area.
