Reconfigurable devices are expected to be utilized in the mission-critical fields such as space development, because a system update and a pseudo-repair can be achieved remotely by reconfiguration. However, conventional reconfigurable devices suffer from memory bit upsets caused by charged particles in space that result in fatal system troubles.This paper proposes an autonomous repair mechanism against configuration upsets for fault-tolerant reconfigurable devices. In proposed architecture, devices consist of 'Autonomous-Repair Cells' with built-in (not reprogrammable) error recovery circuits. Each cell realizes a part of the system's functionality, and guarantees fault tolerance against upset of its own configuration memory. In this paper, four types of Autonomous-Repair Cells are designed and then average lifetime is analyzed. Two of cells are based on TMR (Triple Module Redundancy) and the others are based on EDAC (Error Detection and Correction). In a severe situation where a conventional reconfigurable device with 1Mbit configuration data can achieve only 1-minute average lifetime against configuration upsets, all proposed cells can achieve more than 100 years. |
