Micro-architectural Analysis of OLAP: Limitations and Opportunities

Understanding micro-architectural behavior is important for efficiently using hardware resources. Recent work has shown that in-memory online transaction processing (OLTP) systems severely underutilize their core micro-architecture resources [29]. Whereas, ...

Automatic Application of Power Analysis Countermeasures

Paolo Ienne, Francesco Regazzoni, Philip Brisk, David Novo Bruna, Ali Galip Bayrak

We introduce a compiler that automatically inserts software countermeasures to protect cryptographic algorithms against power-based side-channel attacks. The compiler first estimates which instruction instances leak the most information through side-channe ...

Synchrotron X Ray Induced Axonal Transections in the Brain of Rats Assessed by High-Field Diffusion Tensor Imaging Tractography

Yohan Van de Looij

Since approximately two thirds of epileptic patients are non-eligible for surgery, local axonal fiber transections might be of particular interest for them. Micrometer to millimeter wide synchrotron-generated X-ray beamlets produced by spatial fractionatio ...

Neural Network based On-Chip Thermal Simulator

David Atienza Alonso, Pratyush Kumar

With increasing power densities, runtime thermal management is becoming a necessity in today’s systems, especially so for highly integrated Multi-Processor Systems-on-Chip (MPSoCs). In this paper, we propose a neural network (NN) based approach to implemen ...

Joint Hardware-Software Leakage Minimization Approach for the Register File of VLIW Embedded Architectures

Giovanni De Micheli, David Atienza Alonso, José Luis Ayala Rodrigo

New applications demand very high processing power when run on embedded systems. Very Long Instruction Word (VLIW) architectures have emerged as a promising alternative to provide such processing capabilities under the given energy budget. However, in this ...

Exploring Temperature-Aware Design of Memory Architectures in VLIW Systems

David Atienza Alonso, José Luis Ayala Rodrigo

This paper presents a thermal model to analyze the temperature evolution in the shared register files found on VLIW systems. The use of this model allows the analysis of several factors that have an strong impact on the heat transfer: layout topology, plac ...

Reduction of Register File Delay Due to Process Variability in VLIW Embedded Processors

Giovanni De Micheli, David Atienza Alonso, José Luis Ayala Rodrigo

Process variation in future technologies can cause severe performance degradation since different parts of the shared Register File (RF) in VLIW processors may operate at various speeds. In this paper we present a complete approach that handles speed varia ...

Optimal Loop-Unrolling Mechanisms and Architectural Extensions for an Energy-Efficient Design of Shared Register Files in MPSoCs

David Atienza Alonso, José Luis Ayala Rodrigo, Roman Hermida Correa

In this paper we introduce a new hardware/software approach to reduce the energy of the shared register file in upcoming embedded architectures with several VLIW processors. This work includes a set of architectural extensions and special loop unrolling te ...
