Abstract
In this paper a pipelined carry-dependent sum adder with the self-checking structure is proposed. The adder includes four 8-bit carry-dependent sum adder (CDSA) , a 4-bit block carry look-ahead unit (BCLU) and a parity checker. The necessary area of the proposed adder is only about 3.85% over the traditional ripple carry adders, while the sum of the traditional adders is delayed by 39.2% with respect to the proposed adder for 32-bit implementation
