Low Complexity Concurrent Error Detection for Complex Multiplication
Found in: IEEE Transactions on Computers
By Salvatore Pontarelli,Pedro Reviriego,Chris J. Bleakley,Juan Antonio Maestro
Issue Date:September 2013
pp. 1899-1903
This paper studies the problem of designing a low complexity Concurrent Error Detection (CED) circuit for the complex multiplication function commonly used in Digital Signal Processing circuits. Five novel CED architectures are proposed and their computati...
SYSCORE: A Coarse Grained Reconfigurable Array Architecture for Low Energy Biosignal Processing
Found in: Field-Programmable Custom Computing Machines, Annual IEEE Symposium on
By Kunjan Patel, Séamas McGettrick, Chris J. Bleakley
Issue Date:May 2011
pp. 109-112
The promise of 24/7 patient monitoring and online diagnosis using wearable and implantable biomedical devices has engendered significant research interest in the development of low power biosignal processing platforms. A novel Coarse Grained Reconfigurable...
Soft error detection and correction for FFT based convolution using different block lengths
Found in: On-Line Testing Symposium, IEEE International
By Pedro Reviriego, Juan Antonio Maestro, Anne O'Donnell, Chris J. Bleakley
Issue Date:June 2009
pp. 138-143
The structure of radix-2 Fast Fourier Transforms of length 2<sup>n</sup> where n is an integer is used to propose a new soft error detection and correction scheme for transform based convolution. The scheme can provide up to 100% detection and ...
Failure detection in wireless sensor networks: A sequence-based dynamic approach
Found in: ACM Transactions on Sensor Networks (TOSN)
By Abu Raihan M. Kamal, Chris J. Bleakley, Simon Dobson
Issue Date:January 2014
pp. 1-29
Wireless Sensor Network (WSN) technology has recently moved out of controlled laboratory settings to real-world deployments. Many of these deployments experience high rates of failure. Common types of failure include node failure, link failure, and node re...
Congestion mitigation using in-network sensor datasummarization
Found in: Proceedings of the 9th ACM symposium on Performance evaluation of wireless ad hoc, sensor, and ubiquitous networks (PE-WASUN '12)
By Abu Raihan M. Kamal, Chris J. Bleakley, Simon Dobson
Issue Date:October 2012
pp. 93-100
Congestion can occur in Wireless Sensor Networks due to simultaneous event detection at multiple nodes, link failure or node failure. Most previously proposed congestion mitigation algorithms rely on rate control protocols to reduce network traffic. Typica...
Reliability analysis of memories protected with BICS and a per-word parity bit
Found in: ACM Transactions on Design Automation of Electronic Systems (TODAES)
By Chris J. Bleakley, Juan Antonio Maestro, Pedro Reviriego
Issue Date:February 2010
pp. 1-15
This article presents an analysis of the reliability of memories protected with Built-in Current Sensors (BICS) and a per-word parity bit when exposed to Single Event Upsets (SEUs). Reliability is characterized by Mean Time to Failure (MTTF) for which two ...
