ABSTRACT:
In a device control apparatus, a processor that operates according to software, an OS storage unit stores Operating Systems that operate on the processor, and a storage unit stores privileged software which operates on the processor. The privileged software calls one of the Operating Systems when the processor receives an interrupt from a device, and the Operating System controls the device. Furthermore, a detecting unit detects an interrupt to the processor, a judging unit judges whether the Operating System has called the privileged software from the storage unit in a first predetermined time from detection of the interrupt, and a resetting unit resets the processor when the judging unit judges that the Operating Systcm 9em has not called the privileged software from the storage unit.
