Let X be one of the last two terms that can represent mmultiplier with zero padding as. Verilog Search for additional papers on this topic. The results and discussions of the proposed reversible Baugh-Wooley multiplier are presented in section 5. This work also involves two steps as in [5].

Discrete wooleg transform Carry-select adder Performance Evaluation Digital data. The organization of the paper is as follows. Therefore, it is clear that this is the better design than the existing counterparts. The conclusion of the above discussion is that, it is evident that the proposed reversible Baugh-Wooley multiplier circuit design is better than the existing designs with respect to gate counts, garbage inputs and garbage outputs.
In the second step, the multi operand addition, Peres gates and Double Peres gates have been used. Since this is an incompletely specified reversible logic gates the functions Q and R are not specified. In this work we are proposing two reversible multiplier cells representing black and grey cells. Apart from that the reversible logic circuit should use 1 lowest number of reversible gates, 2 lowest number of garbage multoplier, 3 lowest number multipleir constant inputs.
Then the four operand addition has been performed using Peres gates and Double Peres gates. This gate has been used in the partial product generation.
The number of inputs and outputs are three in count; if the first two bits A and B are set, the third bit will be inverted, otherwise all bits will keep on the same value. One of the efficient algorithms to mmultiplier such situation is the Baugh-Wooley multiplication. Efficient realization of large size two’s complement multipliers using embedded blocks in FPGAs.

The yellow cells represent the full adder. Since in reversible circuits the fan-out greater that one is not permitted, this gate is useful for duplicating the inputs. In the block diagram shown in Figure 5three types of cells are used. The multiplier A and the multiplicand B can be represented as.
HNG gates are used in the second step, Multi operand addition. From This Paper Figures, tables, and topics from this paper. To generate the partial products, 16 Peres gates have wioley used, for multplier one-bit multiplication arrays. The number of two-Qubit gates is Hence the proposed Baugh- Wooley Multiplier design is better than existing designs.
Topics Discussed in This Paper. These proposed multiplier cells are having one constant input. This design is useful in the multiplier design with reduced woloey of gates and constant inputs. The Toffoli gate synthesis of the proposed reversible multiplier cell is also given.
World Applied Sciences Journal, 3, The PFAG gate is used in the multi operand addition. Truncated multiplication multiplied approximate rounding E. Data-dependent truncation scheme for parallel multipliers E KingE. Computer arithmetic – algorithms and hardware designs Behrooz Parhami The Quantum cost is The number of output of the reversible gate that is not making useful functions is referred as garbage output.
In the recent years various reversible multiplier designs have been proposed [5] – mutliplier.

Reversible multiplier cell MC. The work [7] also follows the same strategy as the previous two works, multiplication in two steps. The quantum circuits can be constructed only mu,tiplier reversible logic gates.
A Fixed-Width Modified Baugh-Wooley Multiplier Using Verilog
It has been done in two steps as follows: The functions S and T will produce sum and carry outputs respectively of the complement function of the Baugh- Wooley structure. These reversible multiplier cells are targeted for reversible Baugh-Wooley multiplier design. The input A is the multiplier bit. The proposed Baugh-Wooley multiplier design requires 20 gates. Low error fixed-width CSD multiplier with efficient sign extension. The grey cells represent the multiplier cell. The number of gates, constant inputs and garbage outputs.
Hence this bauggh also called as Swap gate.
Design of Compact Baugh-Wooley Multiplier Using Reversible Logic
They produce two outputs namely sum output diagonal-black line and carry output vertical black line. One of the major factors in the design of a reversible logic circuit is the number of constant inputs. The functionality of the multiplier cell was verified with Wokley viewer.
