MTTF-aware design methodology for adaptive voltage scaling
2018 China Semiconductor Technology International Conference (CSTIC), 2018Adaptive voltage scaling (AVS) is a promising approach to overcome manufacturing variability, dynamic environmental fluctuation, and aging. This paper focuses on design of AVS circuits. For pursuing efficient AVS, this work presents a design methodology that optimizes both voltage-scaled circuit and voltage control logic achieving practical long mean ...

Conditional MTTF and its computation in Markov reliability models
Annual Reliability and Maintainability Symposium 1993 Proceedings, 2002The authors discuss the notion of conditional MTTF (mean time to failure) and develop an efficient computational method for the absorption probability and conditional MTTF in a finite state-space Markov model. The method requires the solution of two systems of linear equations of size n, where n is the number of transient states in the Markov chain ...

Determinations of MTTF from the Transition Probability Matrix & Diagram
IEEE Transactions on Reliability, 1978In designing complex repairable systems it is often important to assess system MTTF for a variety of component reliability characteristics and repair capabilities. Two procedures are given for systems for which a state transition diagram is possible. The first allows such calculation to be perforned iteratively without solving each time the system of ...

Improvement of MTTF of feedforward neural networks by applying relearning
Electronics and Communications in Japan (Part II: Electronics), 2002AbstractMany neural networks have been studied, most of them using computer simulations, as a source of new computational paradigms. Since most implementations of neural networks require many elemental components, it is necessary to use a fault‐tolerance mechanism with them.

A New Technique for MTTF Estimation in Highly Reliable Markovian Systems
Monte Carlo Methods and Applications, 1998A new method for the importance sampling simulation of highly reliable Markovian systems is presented. The method has the bounded relative error for balanced and under an additional assumption, unbalanced systems. It has shown very high efficiency in the estimation of the mean time to failure (MTTF) of a system, which is a measure of great importance ...

MTTF-Aware Reliability Task Scheduling for Heterogeneous Multicore System
2015With silicon technology aggressively scaling, the aging-induced long-term reliability becomes the prominent problem of integrated circuits. The reliability of homogeneous multi-core system is improved and the aging is relieved through balancing the workload between cores.

Analytical method for reliability and MTTF assessment of coherent systems with dependent components
Reliability Engineering & System Safety, 2007This paper discusses engineering systems with structural as well as failure dependence among their components. Using the Markov process approach, a coherent system of components with multivariate phase type life distribution is introduced to model the components working in a common random environment. The phase type model is flexible enough to comprise

Update on MTTF figures for linear and rotary coolers of Thales Cryogenics
SPIE Proceedings, 2012Thales Cryogenics has an extensive background in delivering linear and rotary coolers for military, civil and space programs. During the last years several technical improvements have increased the lifetime of all Thales coolers resulting in significantly higher Mean Time To Failure (MTTF) figures.

Estimates of MTTF and optimal number of spares of fault-tolerant processor arrays
[1990] Digest of Papers. Fault-Tolerant Computing: 20th International Symposium, 2002Reliability and mean-time-to-failure (MTTF) models of different fault-tolerant processor arrays (FTPAs) are introduced. On the basis of these models, approaches which allow for the analytical estimate of the necessary number of spares (NNS) and the optimal number of spares (ONS) are proposed.
