Abstract
In this paper, a new self-checking code-disjoint Booth-2 multiplier with an improved error detection and with a reduced area overhead is proposed. Compared to the 64 times 64 multiplier without error detection the area for the proposed multiplier increases for the different implementations only by 23%-30%. Especially for soft errors the error detection capability is significantly improved. All even or odd (soft) errors in the output registers are detected
