A New Multiplier Using Wallace Structure and Carry Select Adder with Pipelining

نویسنده

  • Reza Hashemian
چکیده

Design of a high performance and high-density multiplier is presented. This multiplier is constructed by using the Wallace tree structure with pipelining. A fast carry select adder is used for the final two-operand adder. It is shown that the time delay for the entire multiplier is O(log(n)). The design is particularly carried out for a 32-bit multiplier with two sections of pipelining, to balance the delays through the multiplier. A total of ten gate delays is all needed for the multiplication throughput. Index Terms – Multiplier, Wallace structure, Carry-select adder, Pipelining.

Modified Booth Multiplier with Carry Select Adder using 3-stage Pipelining Technique

This paper presents a high-speed and low area 16 ×16 bit Modified Booth Multiplier (MBM) by using Carry Select Adder (CSA) and 3-stage pipelining technique. CSA improves the performance of MBM and pipelining technique reduces the delay time. Using these techniques, the delay is reduced by 56% and the numbers of SLICES and LUT's are reduced by 4% as compared to high speed MBM. The multiplie...
