<P>PROBLEM TO BE SOLVED: To reduce the current consumption of a counter circuit while keeping the speed of counter operation intact. <P>SOLUTION: In each counter circuit CU, starts and stops of counting actions on S clocks CK<SB POS="POST">1</SB>-CK<SB POS="POST">s</SB>are sequentially propagated, so that in the process of the counting action on the clock CK<SB POS="POST">n</SB>, the counting actions on the clocks CK<SB POS="POST">1</SB>-CK<SB POS="POST">n-1</SB>, CK<SB POS="POST">n+1</SB>-CK<SB POS="POST">s</SB>are stopped. <P>COPYRIGHT: (C)2012,JPO&INPIT |
