It is an interesting paper using relatively new encoding scheme for multiplier design.
Can I kindly seek you opinions –
1. It looks that CCM is a very good case study for unary representation, am I right?
2. For large coefficient cases, does HBU lead to higher error (Fig.7)? Could you please share some observation on your error comparisons versus LUT-based and shift-and-add based CCMs?
3. One interesting point is why HBU’s area drops at larger coefficient cases?

Thank you very much.
