The power gating technique is useful in reducing standby leakage current, but it increases the gate delay. For a functional unit, its maximum allowable delay (for a target clock period) limits its smallest standby leakage current its power gating can achieve. In this paper, we point out that, in the high-level synthesis of a nonzero clock skew circuit, the resource binding (including functional...

In modeling a cold standby redundancy allocation problem (RAP) with imperfect switching mechanism, deriving a closed form version of a system reliability is too difficult. A convenient lower bound on system reliability is proposed and this approximation is widely used as a part of objective function for a system reliability maximization problem in the literature. Considering this lower bound do...

In the literature, some schemes were proposed to combine Multi-Threshold CMOS (MTCMOS) with asynchronous circuits to reduce standby power consumption. However, all of these can only be applied to asynchronous circuits in which the values of all signals can be determined in the standby state. As a result, their applications are limited. To solve this problem, this paper develops standby power re...

The safety of electric vehicles has the highest priority because it helps contribute to customer confidence and thereby ensures further growth of the electromobility market. Therefore in series production redundant hardware concepts like dual core microcontrollers running in lock-step-mode are used to reach ASIL D safety requirements given from the ISO 26262. Coded processing is capable of redu...

Operating systems do not perform their intended functions as time passes and ultimately fail due the failure of one or more of their parts, units, or components. Failure is caused by many factors such as age, deterioration, wear and tear, leakage, and lack of proper and timely maintenances. Failed components are usually replaced if not expensive or critical; otherwise repaired. Repair can be pe...

The problem of reliability of new object of distributed hardware software (DHS) multi-agent system (MAS) is considered. DHS MAS is determined as a system that is based on agent technologies and consists of both agents and hardware components required for execution of agents and for interaction of agents with an environment. Reliability improvement, fault-recovery and several reliability assessm...

This paper deals with a stochastic model for a two-unit hot standby combined hardware-software system in which one unit is operative and the other is hot standby. The operative unit may have hardware or software failures and goes to repair. This leads to degradation of the system and then hot standby unit is under operation. Further on hardware or software failures of the hot standby unit the s...
