On the Practicality of Intrinsic Reconfiguration As a Fault Recovery Method in Analog Systems [article]

Garrison W. Greenwood
2004 arXiv   pre-print
The focus of previous evolvable hardware research relating to fault-tolerance has been primarily restricted to restoring functionality, with no real consideration of time constraints.  ...  This framework has generated an interest in using evolvable hardware for fault-tolerant systems because reconfiguration can effectively deal with hardware faults whenever it is impossible to provide spares  ...  One way of increasing a system's availability is to make it fault-tolerant-i.e., capable of detecting and recovering from hardware faults.  ...

A (Fault-Tolerant)2 Scheduler for Real-Time HW Tasks [chapter]

Xabier Iturbe, Khaled Benkrid, Tughrul Arslan, Mikel Azkarate, Imanol Martinez
2011 Lecture Notes in Computer Science  
This paper describes a fault-tolerant scheduler that uses the Area-Time response Balancing algorithm (ATB) for scheduling real-time hardware tasks onto partially reconfigurable FPGAs.  ...  Besides the scheduling circuit is itself fault-tolerant, ATB is aware of the occurring faults in the silicon substrate of the chip, leading to a very reliable "fault-tolerant square scheduling".  ...  Conclusions We have described a fault-tolerant architecture for the ATB scheduler.  ...
