The hardware redundancy costs required for self-healingsystems increase with system complexity, creatingconcerns about the cost-feasibility of large-scaleautonomic systems. Redundancy costs can be minimizedwithout reducing reliability by providing finest-grainedfault recovery, but modern redundancy techniques are noteffective for sub-component-level recovery.This paper introduces a design technique for low-cost,fine-grained self-healing hardware. Small amounts ofreconfigurable logic are integrated within primarilyfixed-logic circuits to provide heterogeneous redundancyfor efficient fine-grained, self-contained fault detection,diagnosis, and recovery. When combined with traditionalcoarse-grained recovery techniques for larger failures,this technique enables large-scale self-healing systemswith reduced redundancy costs.
