Error Control Schemes for On-chip Communication Links: the energy-reliability trade-off

Giovanni De Micheli, Luca Benini

On-chip interconnection networks for future systems on chip (SoC) will have to deal with the increasing sensitivity of global wires to noise sources such as crosstalk or power supply noise. Hence, transient delay and logic faults are likely to reduce the r ...

Locally Testable Codes

Mahdi Cheraghchi Bashi Astaneh

Error correcting codes are combinatorial objects that allow reliable recovery of information in presence of errors by cleverly augmenting the original information with a certain amount of redundancy. The availability of efficient means of error detection i ...

Single and Multi-Hop ARQ in Sensor Networks

Martin Vetterli, Henri Julien Dubois-Ferrière

We present a novel error-correction scheme for sensor networks called Multi-hop Hybrid ARQ (MHARQ). Rather than immediately discard a received corrupt packet, a node buffers it. When two corrupt versions of a packet have been received, a procedure attempts ...

Analysis of Error Recovery Schemes for Networks on Chips

Giovanni De Micheli, Luca Benini, Srinivasan Murali

In this article, we discuss design constraints to characterize efficient error recovery mechanisms for the NoC design environment. We explore error control mechanisms at the data link and network layers and present the schemes' architectural details. We in ...

Concatenated codes for block-fading channels

Albert Guillén i Fàbregas

In this thesis we study coding strategies for single-user block-fading channels. The block-fading channel is a simplified model of slowly varying wireless communication channels with stringent delay constraints. This model is particularly important in prac ...

Low-density parity-check codes with rates very close to the capacity of the q-ary symmetric channel for large q

Mohammad Amin Shokrollahi

Transmission of packets over computer networks is subject to packet-level errors, which appear as "bursts" of bit-level errors and are not well modeled by memoryless binary channels. A standard scrambling technique is used for transmission of packets by th ...

Algebraic-geometric codes on the erasure channel

Mohammad Amin Shokrollahi, Andrew Brown

This paper investigates the use of algebraic-geometric codes for data transmission over a packet network, by comparing their encoding/decoding speeds to those of the ubiquitous Reed-Solomon Codes. We take advantage of the fact that AG codes allow the const ...

Fingerprinting: Bounding the Soft-Error Detection Latency and Bandwidth

Babak Falsafi

Recent studies have suggested that the soft-error rate in microprocessor logic will become a reliability concern by 2010. This paper proposes an efficient error detection technique, called fingerprinting, that detects differences in execution across a dual ...

Effect of Recognition Errors on Information Retrieval Performance

Alessandro Vinciarelli

This work shows experiments on the retrieval of handwritten documents. The performance of the same state-of-the-art Information Retrieval system is compared when dealing with manual (no errors) and automatic (Word Error Rate around 50%) transcriptions of t ...
