Abstract We propose a power-aware ECC (Error Correction Code) register without hurting the reliability of data caches. The ECC register replaces the complicated ECC array used in traditional data caches. While the traditional ECC in the ECC array is dedicated to one cache line, the proposed ECC register is shared by all the cache lines, which significantly reduces leakage power consumed in the ...

This paper describes the design and evaluation of two software implemented error detection and system recovery mechanisms that protect a prototype brakeby-wire controller from soft errors. We used an evaluation driven design process to develop the software mechanisms, which are specifically designed to prevent soft errors from causing critical failures in the brake controller. The design proces...

A novel multiuser detection scheme applying iterative soft-interference cancellation in multi-carrier code division multiple access (MC-CDMA) systems is proposed and investigated. The novel detection scheme cancels the interference from the other users by taking into account reliability informations about the detected interference. For this purpose, we use not the decisions from the inner decod...

Title of dissertation: PERFORMANCE ANALYSIS OF ALGEBRAIC SOFT-DECISION DECODING OF REED-SOLOMON CODES Andrew Duggan, Masters of Science, 2006 Thesis directed by: Professor Alexander Barg Department of Electrical and Computer Engineering We investigate the decoding region for Algebraic Soft-Decision Decoding (ASD) of Reed-Solomon codes in a discrete, memoryless, additive-noise channel. An expres...

This paper focuses on the study of the error composition of a fuzzy decision tree induction method recently proposed by the authors, called soft decision trees. This error may be expressed as a sum of three types of error: residual error, bias and variance. The paper studies empirically the tradeo between bias and variance in a soft decision tree method and compares it with the tradeo of classi...

The word error probability of binary linear block codes is evaluated in Rayleigh fading channels with diversity reception far three decoding algorithms: error correction (EC), errorlerasure correction (EEC). and maximum likelihood (MLI soft decoding algorithms. The performance advantage of EEC over EC In the required average SNR decreases as the number of ditersity channels increases. The perfo...

Perceptrons with graded input-output relations and a limited output precision are studied within the Gardner–Derrida canonical ensemble approach. Soft non-negative error measures are introduced allowing for extended retrieval properties. In particular, the performance of these systems for a linear and quadratic error measure, corresponding to the perceptron respectively the adaline learning alg...

Manuscript received May 1, 2009; revised July 1, 2009; accepted July 3, 2009. Abstract—Network coding in wireless network can improve network throughput by exploiting the broadcast nature of the wireless network. Taking into consideration the error prone nature of wireless networks, we investigate the design of network coding implemented in physical layer, and propose a cooperative network codi...

In this paper, we consider a cognitive radio network containing two cognitive radios (CRs) and one primary user. The CRs utilize finite number of received data samples for estimating the energy of the primary signals and forward these energy estimates to a fusion center (FC). The FC combines the energy estimates and utilizes a global threshold based on the exact knowledge of local thresholds of...

Memory state can be corrupted by the impact of particles causing single-event upsets (SEUs). Understanding and dealing with these soft (or transient) errors is important for system reliability. Several earlier studies have provided field test measurement results on memory soft error rate, but no results were available for recent production computer systems. We believe the measurement results on...
