Paper: “A Framework for Reliability Assessment and Enhancement in Multi-Processor Systems-On-Chip”

The paper “A Framework for Reliability Assessment and Enhancement in Multi-Processor Systems-On-Chip”, authored by Giovanni Beltrame, Cristiana Bolchini, Luca Fossati, Antonio Miele e Donatella Sciuto has been presented at DFT 2007.

Reliability issues play a relevant role in the design of embedded systems for critical applications; this and the always increasing performance requirements lead to the adoption of new architectural solutions, as shown by the introduction of Multi-Processor Systems-on-Chip (MPSoC).
MPSoCs raise new challenges related to the complexity of the interactions among several independent cores. This paper presents a framework, based on a simulation platform, for the design of this kind of embedded systems; the framework supports the use of reliability techniques in order to address fault detection and tolerance issues. The simulation platform is also adopted for a reliability assessment task, achieved by exploiting fault injection targeting each component of the system and by monitoring the effects on the entire architecture.
