Efficient Partial Redundancy Fault Tolerance Compilation: Replicating Critical Subgraph of Error Flow

Exploiting Instruction Redundancy for Transient Fault Tolerance

This paper presents an approach for integrating fault-tolerance t e chniques into microprocessors by utilizing instruction redundancy as well as time redundancy. Smaller and smaller transistors, higher and higher clock frequency, and lower and lower power supply voltage reduce r eliability of microprocessors. In addition, microprocessors are u s e d in systems which require h i g h d e p endabi...

Exploiting Inherent Program Redundancy for Fault Tolerance

Title of dissertation: Exploiting Inherent Program Redundancy for Fault Tolerance Xuanhua Li, Doctor of Philosophy, 2009 Dissertation directed by: Professor Donald Yeung Department of Electrical and Computer Engineering Technology scaling has led to growing concerns about reliability in microprocessors. Currently, fault tolerance studies rely on creating explicitly redundant execution for fault...

Fault Tolerance with Multiple Task Modular Redundancy

The redundant units in a classic N Modular Redundancy (NMR) system are employed solely for fault tolerance, making this technique inefficient. This paper introduces Multiple Task Modular Redundancy that allows an NMR system to have a higher throughput by exploiting, when no faults have occurred, the system’s redundancy. More than one group of replicated tasks are optimistically executed. This m...

Interprocedural Partial Redundancy Elimination With Application to Distributed Memory Compilation

EVOLUTION OF SHUI - rLE AVIONICS REDUNDANCY MANAGEMENT / FAULT TOLERANCE Jack

The challenge of providing redundancy management (RM) and fault tolerance to meet the Shuttle Program requirements of fail operational/fail safe for the avionics systems was complicated by the critical program constraints of weight, cost, and schedule, This paper addresses the basic and sometimes false effectivity of less than pure RM designs. Evolution of the multiple input selection filter (t...
