<p>In an environment where multiple OSs are present in one processor having a power saving function, a power-saving processor controller has a main OS that accepts a timer interrupt outputted from a hardware timer at a timing when a predetermined time elapses and a sub-OS treated as a task executed by the main OS, judges whether an executable task is present or not at the timing of the timer interrupt, and carries out an interrupt to the sub-OS if any executable task is present in the sub-OS.</p> |
