a new design for 27-2 compressor

implementation of parallel multipliers with operands meeting IEEE754 standard could involve a 27-2 compression of partial products . In this paper we offer a new design which is suitable for low power and high speed processing environment more than 41% of carry-in/carry-out wires are eliminated in our design with the advantage of less carry propagation delay and quite fewer interconnctions leading to faster multi;ocation and less chip area. our multiplier is coded in VHDL and implemented on commercially available EDA tool chain.
