Design and analysis of majority logic-based multipliers in perpendicular nanomagnetic logic

In the process of finding an alternative for CMOS technology, various new technologies have emerged with emphasis on reducing the power consumption. Amongst the various technologies, nanomagnetic logic (NML) serves as a favourable replacement. Nanomagnetic logic is a new computing paradigms for the beyond CMOS technology that uses both memory and logic elements between nanomagnets using field-coupled technology. This paper explores the approximate computing concept in nanomagnetic logic. Approximate computing is an emerging computing paradigm where we can trades-off the power with accuracy. We have put forward two approximate 8-bit Dadda multipliers that have been designed using two different 5:2 approximate compressors using majority-based logic. The effectiveness and efficiency of these multipliers are evaluated using image processing algorithms and comparison with other approximate multipliers.
