Energy-efficient approximate multipliers and adders for multimedia computing applications: Design and evaluation of novel optimized arithmetic circuits with enhanced accuracy

Advanced electronics have become an integral part of human life, from smartphones in our pockets to modern vehicles on the road to satellites orbiting the Earth. Power consumption has become a major constraint in these applications. Approximate computing (AC) has emerged as one of the most promising paradigms and is pe...

Frontier-Aware Compensated Truncated Multiplier for Energy-Efficient Edge-AI VLSI Datapaths

Approximate multiplication is attractive for VLSI accelerators used in image processing, digital signal processing, and edge artificial intelligence because many workloads can tolerate bounded numerical error in exchange for reduced switching and arithmetic complexity. This work presents a frontier-aware compensated tr...

A Study on Stochastic Number Systems and Computing Architectures for Low-Power and Fault-Tolerant VLSI Systems

This paper aims to showcase an in-depth study of a stochastic system that could be used in complex systems rather than going for traditional methods. A stochastic system works with an approximation technique where exact accuracy may be moderately compromised compared with a conventional binary system, but even though w...
