Abstract : In this paper two new schemes of systolic multipliers are proposed, one based on Modified Booth encoding and the other is based on the selection of one of the terms 0, X, 2X, 3X where x is the serial input of the multiplier. The pro-posed multipliers operate with 100% efficiency that is with-out zero words inserted between successive data. Systolisity and the continuous operation are achieved without an in-crease in hardware complexity. The proposed schemes are especially suited for long number multiplication.
