Given the stringent requirements of energy efficiency for Internet-of-Things edge devices,
approximate multipliers, as a basic component of many processors and accelerators, have …

Approximate multipliers attract a large interest in the scientific literature that proposes
several circuits built with approximate 4-2 compressors. Due to the large number of …

Approximate computing is an emerging trend in digital design that trades off the requirement
of exact computation for improved speed and power performance. This paper proposes …

Approximate computing is a new paradigm for designing energy-efficient integrated circuits
at the nanoscale. In this paper, we propose efficient imprecise 4: 2 and 5: 2 compressors by …

Adders play a vital role in the digital signal processing systems. The design of 32-bit adders
is of high importance because 32-bit architecture is common and widely used in many digital …

This paper proposes an energy-efficient approximate multiplier which combines radix-4
Booth encoding and logarithmic product approximation. Additionally, a datapath pruning …

This paper presents the design of approximate 15-4 compressor using 5-3 compressors as
basic module. Four different types of approximate 5-3 compressors are used in a 15-4 …

In this brief, a new binary counter design is proposed. It uses 3-bit stacking circuits, which
group all of the “1” bits together, followed by a novel symmetric method to combine pairs of 3 …

In this paper we propose an energy-efficient approximate multiplier which uses a new
approximate 4-2 compressor. The proposed compressor has a low error probability and its …

This paper proposes a novel approach to build integer multiplication circuits based on
speculation, a technique which performs a faster-but occasionally wrong-operation resorting …
