Abstract:Background: The advent of High Performance Computing (HPC) applications and big data
applications has made it imparitive to develop hardware that can match the computing demands. In
such high performance systems, the high speed multipliers are the most sought after components. A
compressor is an important part of the multiplier; it plays a vital role in the performance of multiplier,
also it contributes to the efficiency enhancement of an arithmetic circuit. The 5:2 compressor circuit
design proposed here improves overall performance and efficiency of the arithmetic circuits in
terms of power consumption, delay and power delay product. The proposed 5:2 compressor circuit
was implemented using both CMOS and Carbon Nano Tube Field Effect Transistor (CNTFET) technologies
and it was observed that the proposed circuit has yielded better results with CNTFETs as
compared to MOSFETs.
Methods/Results: The proposed 5:2 compressor circuit was designed with CMOS technology
simulated at 45 nm with voltage supply 1.0 V and compared it with the existing 5:2 compressor
designes to validate the improvements. Thereafter, the proposed design was implemented with CNTFET
technology at 32 nm and simulated with voltage supply 0.6 V. The comparision results of proposed
5:2 compressor with existing designs implemented using CMOS. The results also compare the
proposed design on CMOS and CNTFET technologies for parameters like power, delay, power delay
product.
Conclusion: It can be concluded that the proposed 5:2 compressor gives better results as compared
to the existing 5:2 compressor designs implemeted using CMOS. The improvement in power, delay
and power delay product is approx 30%, 15% and 40% respectively. The proposed circuit of 5:2
compressor is also implemented using CNTFET technology and compared, which further enhances
the results by 30% (power consumption and PDP). Hence, the proposed circuit implemented using
CNTFET gives substantial improvements over the existing circuits.
