Abstract

PURPOSE:To simplify the whole constitution by adding and/or subtracting the content of the up and down counter for lower bits when the content of the counter for upper bits with the number less than lower bits is transfered to the up and down counter for upper bits by carry or borrow to return its contents to the counter for upper bits.
