A CPU includes a code write unit which writes an interrupt generation code into a page in which the instructions stored in the non-volatile memory are not written, among a plurality of the pages included in an instruction area that is an area of the volatile memory into which the instructions are written, the interrupt generation code being a code for generating a software interrupt, an instruction transfer unit which transfers the instructions from the non-volatile memory to a corresponding page of the volatile memory that is a page in which the interrupt generation code generating the software interrupt is stored when the software interrupt is generated by the interrupt generation code, the instructions being to be stored in the corresponding page, and an instruction execution unit which executes the instructions stored in the instruction area, and when the interrupt generation code is executed, generates a software interrupt.

Under the circumstances that a lock object which performs a restriction control on an exclusive use of a sharable resource is granting a second information processor a right of prior use of the sharable resource over a first information processor, a time length of exclusive use during which the sharable resource is exclusively used by the second information processor is measured when an attempt to acquire the right of prior use requested by the first information processor for the lock object fails, and least two standby operations are set, the at least two standby operations being carried out by the first information processor until the right of prior use of the sharable resource granted to the second information processor is no longer valid, and the time length of exclusive use is compared to a decision threshold value preset for evaluation of the time length of exclusive use so that one of the standby operations suitable for a comparison result is selected.

An information processing device and a mobile terminal include a power consumption calculator which calculates, for each processing executed by the information processing device (or mobile terminal), power consumption information concerning an amount of power consumed by executing each processing. A request generator compares the amount of power indicated by the power consumption information and a remaining amount of power of the information processing device(or mobile terminal), and generates a request to execute predetermined processing according to a result of the comparison. A request processor executes the predetermined processing in response to the generated request.
