A Fault tolerant reversible logic has gained importance as they consume low power and less heat dissipation. The benefits of logical reversibility can be gained only after employing physical reversibility. Every future technology will have to use reversible gates in order to reduce power. This paper proposed a new fault tolerant reversible 4*4 RR-gate which satisfies the reversible and parity p...

Virtualization is an important enabling technology for many large data centers and cloud computing environments, and virtual machine (VM) migration plays a key role in the load balancing among the hosts of the data center. However, the existing load balancing schemes based on VM migration have serious influence on the fault-tolerant level of the services in the data center, and thus the reliabi...

A fault-tolerant gait planning of a quadruped robot is presented. The considered robot has static walking and suffers from a locked joint failure. Especially, the quadruped robot is equipped with the moving appendage onto the body. By controlling the moving appendage, the robot can adjust the effective position of the center of gravity. Incorporating the adjustment of the moving appendage along...

Task synchronization means that each redundant module has the same executing schedule in each task scheduling cycle of the operating system in the Triple Modular Redundancy (abbreviated TMR) fault-tolerant systems; it faces how to realize the coordination among the three modules. Therefore, it is necessary to investigate the task synchronization process of the TMR fault-tolerant system. In the ...

In order to make systems based on nanometerscale devices reliable, the design of fault-tolerant architectures will be necessary. This paper presents a novel fault-tolerant technique for future nanocomputers, NAND multiplexing. Initiated by von Neumann, the NAND multiplexing technique, based on a massive duplication of imperfect devices and randomized imperfect interconnect, had been studied wit...

Many time-critical applications require predictable performance and tasks in these applications have deadlines to be met even in the presence of faults. Three diierent approaches have evolved for fault-tolerant scheduling of real-time tasks in multiprocessor systems-Triple Modular Redundancy (TMR), Primary Backup (PB), and Imprecise Computation (IC). In TMR approach, the fault detection is by v...

International Symposium on Shared Memory Multiprocessing, 1991 20 Fault-Tolerant Design for Multistage Routing Networks Andr e DeHon, Thomas Knight Jr., and Henry Minsky As the size of digital systems increases, the average length of time between single component failures diminishes. To avoid component related failures, large computers must be fault-tolerant; that is, the computer must perform ...

EEcient parallel algorithms proposed to solve many fundamental problems in scientiic computation are sensitive to processor failures. Because of its low costs, algorithm-based fault tolerance i s a n i n t e r esting concept for introducing fault tolerance into existing multi-processors. To facilitate fault{tolerant programming in scientiic computation, we have modiied and developed further an ...

Two fault-tolerant software techniques are investigated: recovery block and N-version programming. For each, the stable reliability model is transformed into a model that considers reliability growth via the transformation approach based on the hyperexponential model. Analytic and numeric processing of the transformed models identify the influence of fault removal on the reliability of the faul...

Distributed real-time and embedded (DRE) systems often require support for multiple simultaneous quality of service (QoS) properties, such as real-timeliness and fault tolerance, that operate within resource constrained environments. These resource constraints motivate the need for a lightweight middleware infrastructure, while the need for simultaneous QoS properties require the middleware to ...
