A context save method, an information processor and an interrupt generator for restoring, after a reset of a CPU, CPU context information such as the interrupt acceptance state of the CPU before the CPU reset. An interrupt controller stores CPU context information set in a CPU in a memory before resetting the CPU. After the reset of the CPU, the interrupt controller reads out the CPU context information stored in the memory. The interrupt controller feeds interrupt acceptance information contained in the CPU context information to the interrupt generator. The interrupt generator generates an interrupt corresponding to the input information. Besides, the interrupt controller sets the CPU context information except for the interrupt acceptance information in the CPU. |
