Design of Approximate Logarithmic Multipliers
Proceedings of the Great Lakes Symposium on VLSI 2017, 2017Lower power has been a main challenge for IC design. Approximate computing provides a new approach for low power design. Logarithmic multiplier (LM) is a kind of approximate multipliers in nature. In this paper, the design of both non-iterative and iterative approximate LMs (IALM) are studied to further reduce the power consumption and improve the ...

Design of An Approximate FFT Processor Based on Approximate Complex Multipliers
2021 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2021The Fast Fourier Transform (FFT) is an efficient algorithm to calculate the Discrete Fourier Transform (DFT), which is often employed in Digital Signal Processing (DSP) and communication. In FFT, complex multiplication and addition units in the butterfly module consume most of the hardware resources.

Approximations to the Multiplier Method
SIAM Journal on Numerical Analysis, 1985The author analyzes approximations to the multiplier method for solving optimization problems. In particular, the effect of replacing the constrained problem by the unconstrained optimization of a penalized Lagrangian over a subspace instead of a Hilbert space, is considered. Some applications to nonlinear optimal control are discussed.

Architectural-space exploration of approximate multipliers
Proceedings of the 35th International Conference on Computer-Aided Design, 2016This paper presents an architectural-space exploration methodology for designing approximate multipliers. Unlike state-of-the-art, our methodology generates various design points by adapting three key parameters: (1) different types of elementary approximate multiply modules, (2) different types of elementary adder modules for summing the partial ...
