This paper presents the design of a novel modified Wallace tree multiplier, using the reversible TSG gate proposed by the authors earlier. The novelty of the TSG gate is that it can also work singly as a reversible full adder. The TSG gate is also used in this paper to design various other reversible arithmetic and logical components that can be assembled to realize a primitive reversible/ quantum ALU. It is also shown that these components are optimal, in terms of number of reversible gates and garbage outputs, compared to other designs existing in literature.
