Abstract:
PROBLEM TO BE SOLVED: To provide a capacity information analysis module and its method capable of reducing workload on a microprocessor and quickly analyzing processing time for storage medium capacity information. SOLUTION: As regards the capacity information analysis module and its method, the capacity information analysis module reads data with an interface unit and supplies the data to a comparison unit for comparison. Subsequently, the comparison unit, after comparing the data, outputs a notification signal, and an accumulation unit accumulates the comparison result from the comparison unit based on the notification signal. By being controlled with a control unit by a setting signal supplied from the microprocessor for respective units, the analysis time for the capacity information is shortened and the load on the microprocessor is reduced.
