SABRE: a bio-inspired fault-tolerant electronic architecture.

Area of Science:

• Computer Science
• Bio-inspired Engineering
• Reliability Engineering

Background:

• Modern electronic systems face increasing complexity and reliability challenges.
• Biological systems exhibit remarkable fault tolerance and reliability despite their complexity.
• There is a need for novel architectures to enhance electronic system dependability.

Purpose of the Study:

• To design a bio-inspired hierarchical architecture for highly reliable and fault-tolerant electronic systems.
• To introduce SABRE (self-healing cellular architectures for biologically inspired highly reliable electronic systems).
• To investigate how biological principles can be applied to electronic system design for improved fault tolerance.

Main Methods:

• Development of a hierarchical architecture with multiple layers of fault tolerance.
• Implementation of cellular-level fault detection and self-repair mechanisms.
• Integration of transport triggered architectures (TTA) for partial-dynamic reconfiguration.
• Application of coarser-grain reconfiguration at the multi-processor system level.

Main Results:

• The SABRE architecture demonstrates a multi-layered approach to fault tolerance.
• Each cellular component can detect and initiate repairs for internal faults.
• The system utilizes dynamic reconfiguration at cellular and TTA levels to overcome localized failures.
• Higher-level reconfiguration strategies address processor failures within the multi-processor system.

Conclusions:

• The SABRE architecture effectively leverages bio-inspired principles for robust fault tolerance.
• The hierarchical design enables systemic resilience against various levels of electronic system failures.
• This approach offers a promising direction for developing highly reliable and fault-tolerant electronic systems.
