(a) Synthesis (Pre-layout) results;
(b) PnR (Post-layout) results;
(c) Actual numbers published are scaled down from(130nm, 1.5V) to (32nm, 1.05V) using the formulas used in [5] for comparison
Conclusion: The proposed simple radix-8 structure is very promising with faster sign number multiplication compared to recently published work for wider designs. Designing the wider multipliers with higher radix structures further improves the speed performance with reduction in power consumption and design area.
