Abstract :
Addition is ubiquitous in computer systems, and rising error rates make error detection within adders increasingly important. This paper considers the best way to introduce strong, non-intrusive error detection to fixed-point addition within an existing, optimized machine datapath. A flexible family of separable error detection techniques called carry-propagate/carry-free (CP/CF) duplication is presented that offer superior error detection efficiency for a variety of adders.
