A remark on carry-free binary multiplication
Wolfgang Rülling · IEEE Journal of Solid-State Circuits · 2003
It is shown that any binary multiplier needs some mechanism for carry propagation. As a consequence, the carry-free multiplier presented in the paper by Kim et al. (see IEEE J. Solid-State Circuits, vol. 36, p. 1538-1544, Oct. 2001) cannot work correctly. To demonstrate that fact, implementation-independent test patterns are constructed.
