Energy-Aware Processing Platform Exploration for Embedded Biosignal Analysis

Ahmed Yasir Dogan

According to the World Health Organization, lifestyle-related diseases, e.g., cardiovascular diseases are the major cause of mortality worldwide. An accurate and continuous medical supervision is highly required for diagnosis and treatment of such diseases ...

Reducing OLTP Instruction Misses With Thread Migration

Anastasia Ailamaki, Pinar Tözün

During an instruction miss a processor is unable to fetch instructions. The more frequent instruction misses are the less able a modern processor is to find useful work to do and thus performance suffers. Online transaction processing (OLTP) suffers from h ...

NOC-Out: Microarchitecting a Scale-Out Processor

Babak Falsafi, Boris Robert Grot, Pejman Lotfi Kamran

Scale-out server workloads benefit from many-core processor organizations that enable high throughput thanks to abundant request-level parallelism. A key characteristic of these workloads is the large instruction footprint that exceeds the capacity of priv ...

Low-power processor architecture exploration for online biomedical signal analysis

David Atienza Alonso, Andreas Peter Burg, Luca Benini, Jeremy Hugues-Felix Constantin, Ahmed Yasir Dogan

In this study, the authors explore sequential and parallel processing architectures, utilising a custom ultra-low-power (ULP) processing core, to extend the lifetime of health monitoring systems, where slow biosignal events and highly parallel computations ...

Simulation of High-Performance Memory Allocators

David Atienza Alonso

This study presents a single-core and a multi-core processor architecture for health monitoring systems where slow biosignal events and highly parallel computations exist. The single-core architecture is composed of a processing core (PC), an instruction m ...

Tight Failure Detection Bounds on Atomic Object Implementations

Rachid Guerraoui

This article determines the weakest failure detectors to implement shared atomic objects in a distributed system with crash-prone processes. We first determine the weakest failure detector for the basic register object. We then use that to determine the we ...

Performance Analysis of the SHA-3 Candidates on Exotic Multi-core Architectures

Joppe Willem Bos

The NIST hash function competition to design a new cryptographic hash standard 'SHA-3' is currently one of the hot topics in cryptologic research, its outcome heavily depends on the public evaluation of the remaining 14 candidates. There have been several ...

Distributed Compressed Sensing for Sensor Networks Using Thresholding

Pierre Vandergheynst, Mohammad Golbabaee

Distributed compressed sensing is the extension of compressed sampling (CS) to sensor networks. The idea is to design a CS joint decoding scheme at a central decoder (base station) that exploits the inter-sensor correlations, in order to recover the whole ...

Improving instruction cache performance in OLTP

Anastasia Ailamaki

Instruction-cache misses account for up to 40%; of execution time in online transaction processing (OLTP) database workloads. In contrast to data cache misses, instruction misses cannot be overlapped with out-of-order execution. Chip design limitations do ...
