Semantically-Oriented Mutation Operator in Cartesian Genetic Programming for Evolutionary Circuit Design

no code implementations23 Apr 2020 David Hodan, Vojtech Mrazek, Zdenek Vasicek

Considering the multiplier design problem, for example, the 5x5-bit multiplier represents the most complex circuit evolved from a randomly generated initial population.

Adaptive Verifiability-Driven Strategy for Evolutionary Approximation of Arithmetic Circuits

no code implementations5 Mar 2020 Milan Ceska, Jiri Matyas, Vojtech Mrazek, Lukas Sekanina, Zdenek Vasicek, Tomas Vojnar

We present a novel approach for designing complex approximate arithmetic circuits that trade correctness for power consumption and play important role in many energy-aware applications.

TFApprox: Towards a Fast Emulation of DNN Approximate Hardware Accelerators on GPU

1 code implementation21 Feb 2020 Filip Vaverka, Vojtech Mrazek, Zdenek Vasicek, Lukas Sekanina

In order to address this issue, we propose an efficient emulation method for approximate circuits utilized in a given DNN accelerator which is emulated on GPU.

ALWANN: Automatic Layer-Wise Approximation of Deep Neural Network Accelerators without Retraining

1 code implementation11 Jun 2019 Vojtech Mrazek, Zdenek Vasicek, Lukas Sekanina, Muhammad Abdullah Hanif, Muhammad Shafique

A suitable approximate multiplier is then selected for each computing element from a library of approximate multipliers in such a way that (i) one approximate multiplier serves several layers, and (ii) the overall classification error and energy consumption are minimized.

Automated Circuit Approximation Method Driven by Data Distribution

no code implementations11 Mar 2019 Zdenek Vasicek, Vojtech Mrazek, Lukas Sekanina

We propose an application-tailored data-driven fully automated method for functional approximation of combinational circuits.

autoAx: An Automatic Design Space Exploration and Circuit Building Methodology utilizing Libraries of Approximate Components

2 code implementations22 Feb 2019 Vojtech Mrazek, Muhammad Abdullah Hanif, Zdenek Vasicek, Lukas Sekanina, Muhammad Shafique

Because these libraries contain from tens to thousands of approximate implementations for a single arithmetic operation it is intractable to find an optimal combination of approximate circuits in the library even for an application consisting of a few operations.
