Wallace Tree Multiplier. Multiply each bit of one of the arguments by each bit of the other. Wallace tree multiplier consists of three step process in the first step the bit product terms are formed after the multiplication of the bits of multiplicand and multiplier in second step the bit product matrix is reduced to lower number of rows using half and full adders this process continues till the last addition remains in the final step final addition is done using adders to obtain the result.
Wallace trees are combinatorial logic circuits used to multiply binary integers. The wallace tree has three steps. In the conventional wallace tree multiplier the first step is to form partial product array of n2bits.
It was devised by the australian computer scientist chris wallace in 1964.
Wallace multiplier is an efficient parallel multiplier. The wallace tree has three steps. The wallace tree has three steps. It was devised by the australian computer scientist chris wallace in 1964.
