摘要:Abstract- Vedic Mathematics is the ancient methodology of Indian mathematics which has a
unique technique for arithmetic computations based on 16 Sutras (Formulae). Transistor level
implementation (ASIC) of Vedic Mathematics based 32-bit multiplier for high speed low power
processor is reported in this paper. Simple Boolean logic is combined with ‘Vedic’ formulas, which
reduces the partial products and sums generated in one step, reduces the carry propagation from
LSB to MSB. The implementation methodology ensure substantial reduction of propagation delay
in comparison with Wallace Tree (WTM), modified Booth Algorithm (MBA), Baugh Wooley
(BWM) and Row Bypassing and Parallel Architecture (RBPA) based implementation which are
most commonly used architectures. The functionality of these circuits was checked and
performance parameters like propagation delay and dynamic power consumption were calculated
by spice spectre using standard 90nm CMOS technology. The propagation delay of the resulting
32×32 multiplier was only ~1.06 us and consumes ~132 uW power. The implementation offered
significant improvement in terms of delay and power from earlier reported ones.
