Three-Dimensional Networks-on-Chip (3D-NoC) has been presented as an auspicious solution merging the high parallelism of Network-on-Chip (NoC) interconnect paradigm with the high-performance and lower interconnect-power of 3-dimensional integration circuits. However, 3D-NoC systems are exposed to a variety of manufacturing and design factors making them vulnerable to different faults that cause...

FTAG is a functional model for writing fault-tolerant software that is based on attribute grammars. With this approach, a program is written as a series of module decompositions,with provisions for redoing and replicatingmodules used to implement fault-tolerance requirements. The functional nature of the model and the independence of decompositions makes FTAG especially well-suited for implemen...

The paper focuses on the problem of fault tolerance using soft computing techniques. T...

The lack of fault tolerance is becoming a limiting factor for application scalability in HPC systems. The MPI does not provide standardized fault tolerance interfaces and semantics. The MPI Forum’s Fault Tolerance Working Group is proposing a collective fault tolerant agreement algorithm for the next MPI standard. Such algorithms play a central role in many fault tolerant applications. This pap...

This paper addresses the problems of robust fault estimation and fault-tolerant control for Takagi–Sugeno (T–S) fuzzy systems with time delays and unknown sensor faults. A fuzzy augmented state and fault observer is designed to achieve the system state and sensor fault estimates simultaneously. Furthermore, based on the information of on-line fault estimates, an observer-based dynamic output fe...

This paper addresses the problem of robust fault estimation and fault tolerant control of a continuous age structured model of a harvested fishery system. The harvested fish population is represented by TakagiSugeno fuzzy systems, where the effort is used as a control term, the age classes as a states and the quantity of captured fish per unit of effort as a measured output. Under some biologic...

Embedded systems for safety-critical applications often integrate multiple “functions” and must generally be fault-tolerant. These requirements lead to a need for mechanisms and services that provide protection against fault propagation and ease the construction of distributed fault-tolerant applications. A number of bus architectures have been developed to satisfy this need. This paper reviews...

The design of programs for broadcast disks which incorporate real time and fault tolerance requirements is considered A generalized model for real time fault tolerant broadcast disks is de ned It is shown that designing programs for broadcast disks speci ed in this model is closely related to the scheduling of pinwheel task systems Some new results in pinwheel scheduling theory are derived whic...

The design of a fault tolerant system would be enhanced if a rapid prototyping approach could be conceived which allows fault tolerance to be modelled quickly, and faults simulated to analyse the behaviour of the system. This paper concentrates on how a functional specification language, and its environment, can be used to describe and investigate the properties of parallel fault tolerant syste...
