Abstract:
This work presents the first self-checking Booth-3 multiplier and a new self-checking Booth-2 multiplier using parity prediction. We propose a method which combines error-detection of Booth-3 (or Booth-2) decoder cells and parity prediction. Additionally, code disjointness is ensured by reusing logic for partial product generation. Parity prediction is applied to a carry-save-adder with the standard sign-bit extension. ; In this adder almost all cells have odd fanouts and faults are detected by the parity. Only one adder cell has an even fanout in the case of Booth-3 multiplication. Especially, for even-number Booth-2 multipliers parity prediction becomes efficient. Since that prediction slightly differs from previous work which describes CSA-folded adders, formulas to predict the parity are developed here. The proposed multipliers are compared experimentally with existing solutions. Only 102% of the area of Booth-2 without error detection is needed for the self-checking Booth-3 multiplier.
