Abstract

PURPOSE:To reduce the amount of hardware of the hardware monitor, by counting the frequency where a designated specific event occurs to cause a designated specific result. CONSTITUTION:One of even occurrence indication signals 15 concerning the event occurrence frequency counting device is designated by control signal 17 and is selected and output by selecting circuit 11. In the other selecting circuit 12, one of even result signals 16 is designated by control signal 18 and is selected and output. AND between output signals of selecting circuits 11 and 12 is operated in AND gate 13, and counter 14 is counted up by the output. Then, if a certain disc driving device is designated by control signals 17 and 18, the frequency of success of starting of this disc driving device is obtained by counter 14. Thus, the hardware monitor is relaized with a small amount of hardware.
