On-board vehicle diagnostic systems must have low development and hardware costs in order to be viable. Modelbased methods have shown promise since they use analytical redundancy to reduce costly physical redundancy. However, these methods must also be computationally efficient and function accurately even with simple, low-cost models. The approach presented in this paper uses multiple simple m...

Prioritizing tasks in Hard-Real-Time Systems is a problem belonging to NP-hard class. Scheduling and resource allocation in real-time systems are difficult problems due to the timing constraints of the tasks involved. Scheduling policies in hard real-time systems need to ensure that tasks will meet their deadlines under all circumstances, even in the presence of faults. This work presents techn...

This paper proposes an efficient algorithm based on memetic algorithm (MA) for a redundancy allocation problem without component mixing (RAPCM) in a series-parallel system when the redundancy strategy can be chosen for individual subsystems. Majority of the solution methods for the general RAPCM assume that the type of a redundancy strategy for each subsystem is pre-determined and known a prior...

Safety or mission critical applications have to recover from an error within an acceptable time window or it may potentially lead to disastrous effects or higher costs. The usual industrial practice is to employ fault tolerance using hardware redundancy where costs are highly exorbitant depending on the mission. In this paper, we present a framework for adaptive fault tolerance on the commonly ...

In recent decades, transient faults have become a critical issue in modern electronic devices. Therefore, many fault-tolerant techniques have been proposed to increase system reliability, such as active redundancy, which can be implemented in both space and time dimensions. The main challenge of active redundancy is to introduce the minimal overhead of redundancy and to schedule the tasks. In m...

Defect rate in Nanoelectronics is much higher than conventional CMOS circuits. Hardware redundancy can be a suitable solution for fault tolerance in nano level. A voter circuit is a part of a redundancy based fault tolerant system that enables a system to continue operating properly in the event of one or more faults within its components. Robustness of the voter circuit defines the reliability...

Error correction codes provide a mean to detect and correct errors introduced by the transmission channel. Basically there are two categories of codes a).Block codes and b).convolution codes. Both the codes introduce redundancy by adding parity symbols to the message data. Cyclic redundancy check (CRC) codes are the subset of the cyclic codes. The hardware implementation of a CRC is a simple li...

Introduction: The highly reliable systems are often used in most critical applications like Bank transactions, Defense communications, Aerospace applications, etc. The loss will be enormous if these systems fail in the field, i.e., during the operating time. The circuit designers keep researching to build intelligent systems with reliability improvement by adding redundancy like hardware, softw...

Multi-threadingandmultiscaling are two fundamental microarchitecture approaches that are expected to stay on the existing performance gain curve. Both of these approaches assume that integrated circuits with over billion transistors will become available in the near future. Such large integrated circuits imply reduced design tolerances and hence increased failure probability. Conventional hardw...
