We show that our special representation leads to simp le modular arithmetic with arbitrary moduli while using standard arithmetic components such as carrysave and carrypropagate adders that have been extensi vely optimized for area power and a host James Shahana T K K Poulose Jacob and Sreela Sasi Abstract This paper presents a performance analysis of reversible fault tolerant VLSI implementations of carry select and hybrid decimal adders suitable for multidigit BCD addition The designs enabl Fast Signed-Digit Multi-operand Decimal Adders Jeff Rebacz, Erdal Oruklu, Jafar Saniie Department of Electrical and Computer Engineering Illinois Institute of Technology Chicago 226 J.
