IPC: G06F11/28
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To realize an occurrence sequence detection circuit simply by adding a number of circuits to circuits for one event. SOLUTION: A counter 9 is first initialized to 0 by an initialization signal 12, and a comparator 6 compares a 1st event setting register 2 with comparison object data 7.

Hereafter in the same manner, comparison is sequentially performed up to the n-th event, and when the n-th event coincides, a result signal 11 is outputted from the counter 9. Thus, it is possible to detect an occurrence sequence with only one comparator regardless of the number of events.
