PROJECT TITLE :

A Modified Partial Product Generator for Redundant Binary Multipliers - 2016

ABSTRACT:

Because of its high modularity and carry-free addition, a redundant binary (RB) representation can be used when coming up with high performance multipliers. The conventional RB multiplier needs a further RB partial product (RBPP) row, as a result of a mistake-correcting word (ECW) is generated by both the radix-4 Changed Booth encoding (MBE) and also the RB encoding. This incurs in an additional RBPP accumulation stage for the MBE multiplier. In this paper, a new RB changed partial product generator (RBMPPG) is proposed; it removes the extra ECW and hence, it saves one RBPP accumulation stage. Thus, the proposed RBMPPG generates fewer partial product rows than a typical RB MBE multiplier. Simulation results show that the proposed RBMPPG based mostly styles significantly improve the world and power consumption when the word length of every operand in the multiplier is a minimum of 32 bits; these reductions over previous NB multiplier designs incur during a modest delay increase (approximately 5 percent). The facility-delay product can be reduced by up to fifty nine % using the proposed RB multipliers when put next with existing RB multipliers.
