Patent ID: 7535833

Claim:
A statistic counter device comprising: a plurality of base counters; a plurality of standby counters; and a counter management portion which forms extension counters by dynamically linking the standby counters to higher digits of the base counters when the base counters reach a full count or a count before the full count by a fixed range, and releases the link when the extension counters are reset, wherein a total bit number of all of the base counters and all of the standby counters is equal to or more than a value obtained by multiplying a bit number of a counter counting a value obtained by dividing a total count counted by all of the base counters and the extension counters within a predetermined time by a number of the base counters, by the number of the base counters, and is less than a value obtained by multiplying a bit number which a single counter requires for counting the total count by the number of the base counters.
