Abstract :
In this paper, a new code-disjoint totally self-checking carry-select adder, with low area overhead, is proposed which is based on the simplified design of carry-select adders by use of add1-circuits as proposed in (T. Y. Chang et al., IEE Elec. Lett., vol.34, no.22, p.2101-2103, 1998) and (Y. Kim et al., ISCAS, p.218-221, 2001). The area overhead for the proposed adder is only 40% of a traditional carry-select adder without error detection.
