Compressor Partial product reduction Booth multiplier Compressor -- Design and construction Algorithms Measurement -- Conversion tables Link to publisher's homepage at http://www.iasted.org/ In this paper, we attempt to redesign the 4:2 compressors. Since its inception by Weinberger in 1981[1], this concept of compressor has been used in most digital multiplications and multi operand operation scheme. The original of 4:2 compressor has been build using the full adder unit. Hence this compressor is no improvement compare using Wallace tree or other tree structure. Early 90's some designer has modified the 4:2 compressor in order to reduce the critical path. As a result, a worse case to cross a level of 4:2 compressor is 3 XOR [4]. While in this paper, we have redesign 4:2 compressor based on modification of 4:2 compressor [2, 3, 4]. This design has been simulated using Quartus II software to verify the circuit. As a result, total transistor used in our compressor is less 4 than the modified 4:2 compressor and less 2 transistor than the original 4:2 compressor. In term of speed, the critical path of Carry Out signal is same as the original 4:2 compressor. Our compressor is 0.05% faster than modified 4:2 compressor. 2009-08-17T04:25:39Z 2009-08-17T04:25:39Z 2007 Article p.54-57 978-0-88986-656-0 (CD) http://www.actapress.com/Content_of_Proceeding.aspx?proceedingID=435#pages http://hdl.handle.net/123456789/6905 en Proceedings of the 3rd IASTED International Conference on Advances in Computer Science and Technology, (ACST 2007) International Association of Science and Technology for Development (IASTED) / ACTA Press
