Abstract
A status change monitoring apparatus monitors an apparatus to be monitored to indicate a monitoring result. The monitoring apparatus comprises a new data latching unit for latching new data, an old data latching unit for latching old data received before the reception of the new data, a comparing and storing unit for comparing the new data and the old data and for storing a comparison result, and a processing unit for checking the comparison result to determine whether there is a difference between the old data and the new data. The processing unit processes the new data to indicate the monitoring result only when there is a difference between the old data and the new data, thereby shortening the processing time required for comparing.
