Intermediate Address Space: virtual memory optimization of heterogeneous architectures for cache-resident workloads
David Atienza Alonso, Marina Zapater Sancho, Luis Maria Costero Valero, Darong Huang, Qunyou Liu
The increasing demand for computing power and the emergence of heterogeneous computing architectures have driven the exploration of innovative techniques to address current limitations in both the compute and memory subsystems. One such solution is the use ...
2024Preconditioning techniques for generalized Sylvester matrix equations
Sylvester matrix equations are ubiquitous in scientific computing. However, few solution techniques exist for their generalized multiterm version, as they recently arose in stochastic Galerkin finite element discretizations and isogeometric analysis. In th ...
20232D Nanosystems: Applications of 2D Semiconductors for In-Memory Computing
Machine learning and data processing algorithms have been thriving in finding ways of processing and classifying information by exploiting the hidden trends of large datasets. Although these emerging computational methods have become successful in today's ...
EPFL2023Real-Time Nonlinear Model Predictive Control for Fast Mechatronic Systems
This thesis presents an efficient and extensible numerical software framework for real-time model-based control. We are motivated by complex and challenging mechatronic applications spanning from flight control of fixed-wing aircraft and thrust vector cont ...
EPFL2022Lock-in amplified differential phase contrast
Christophe Moser, Timothé Laforest, Damien Claude-Marie Loterie, Chiara Bonati
We introduce a lock-in method to increase the phase contrast in incoherent Differential Phase Contrast (DPC) imaging. The use of a smart pixel detector with in-pixel signal demodulation, paired with synchronized illumination, provides the basis of a bit-ef ...
SPIE-INT SOC OPTICAL ENGINEERING2022Lock-in incoherent differential phase contrast imaging
Christophe Moser, Timothé Laforest, Damien Claude-Marie Loterie, Chiara Bonati
We introduce a lock-in method to increase the phase contrast in incoherent differential phase contrast (DPC) imaging. This method improves the phase sensitivity by the analog removal of the background. The use of a smart pixel detector with in-pixel signal ...
CHINESE LASER PRESS2022Horizontal side-channel full key recovery on ephemeral SIKE
Natacha Yolande Emmanuel Marie Linard de Guertechin, Aymeric Genet, Novak Kaluderovic
This paper describes the first practical single-trace side-channel power analysis of SIKE. The attack exploits the nature of elliptic curve point addition formulas which require the same function to be executed multiple times. We target the three point lad ...
2021Optimization Methods for Control: From Embedded Programmable Hardware to Data-Driven Process Optimization
The research community has been making significant progress in hardware implementation, numerical computing and algorithm development for optimization-based control. However, there are two key challenges that still have to be overcome for optimization-base ...
EPFL2021Exploiting Errors for Efficiency: A Survey from Circuits to Applications
Babak Falsafi, Alexandros Daglis, Eva Darulova, Mattia Cacciotti, Damien Zufferey, Sasa Misailovic
When a computational task tolerates a relaxation of its specification or when an algorithm tolerates the effects of noise in its execution, hardware, system software, and programming language compilers or their runtime systems can trade deviations from cor ...
ASSOC COMPUTING MACHINERY2020Comparison of Subword Segmentation Methods for Open-vocabulary ASR using a Difficulty Metric
Philip Neil Garner, Claudiu-Cristian Musat
We experiment with subword segmentation approaches that are widely used to address the open vocabulary problem in the context of end-to-end automatic speech recognition (ASR). For morphologically rich languages such as German which has many rare words main ...
