摘要
In this paper, approximate adders were proposed for DSP processors. DSP processors are mainly composed of adders and multipliers at bottom level. The power is minimized in transistor level design. Proposed adders have less power dissipation when compared to existing approximate adders. Results have shown that the proposed adders have less PDP with more accuracy. The circuits were simulated in Cadence virtuoso tool under 45 nm CMOS technology. Supply voltage is + 0.5 V.
