Multipliers Based on Approximate Compressors
Micro and Nanosystems, 2021Background: Approximate computing is an emerging trend in recent year that trades off the requirement of exact computation for the improvement of speed and power performance. Objective: Researchers are trying to improve the speed and power performance proposing different algorithm. Method: This paper proposes approximate compressors used for the

A High Accuracy Approximate Multiplier with Error Correction
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020A novel approximate multiplier with tunable accuracy modes which leverages an inaccurate 4 × 4 multiplier is proposed. The inaccurate multipliers achieve a power reduction of 17.98%–34.15% over corresponding accurate designs with a maximal absolute relative error of 22.2%. A Gaussian filter is implemented for image sharpening as a sample assessment and

Sine Approximation with a Gaussian Multiplier
Sampling Theory in Signal and Image Processing, 2007Recently, it was shown with the help of Fourier analysis that by incorporating a Gaussian multiplier into the truncated classical sampling series, one can approximate bandlimited signals of finite energy with an error that decays exponentially as a function of the number of involved samples.

Fixed-Width Multipliers and Multipliers-Accumulators With Min-Max Approximation Error
IEEE Transactions on Circuits and Systems I: Regular Papers, 2013Fixed-width multipliers have two n-bits operands and produce an approximate n-bits results for their product. These multipliers discard part of the partial products matrix, to reduce hardware cost, and employ extra correction functions to reduce approximation error.

High accuracy approximate multiplier with error correction
2013 IEEE 31st International Conference on Computer Design (ICCD), 2013Approximate computing has gained significant attention due to the popularity of multimedia applications. In this paper, we propose a novel inaccurate 4:2 counter that can effectively reduce the partial product stages of the Wallace Multiplier. Compared to the normal Wallace multiplier, our proposed multiplier can reduce 10.74% of power consumption and ...

Stochastic subgradient methods with approximate Lagrange multipliers
2016 IEEE 55th Conference on Decision and Control (CDC), 2016We study the use of approximate Lagrange multipliers in the stochastic subgradient method for the dual problem in constrained convex optimisation. The use of approximate Lagrange multipliers in the optimisation (instead of the true multipliers) is motivated by the fact that it is possible to accurately approximate some non-convex control problems as ...
