Title: A self-healing real-time system based on run-time self-reconfiguration
Issue Date: 2005
Abstract: The new generations of SRAM-based FPGA (Field Programmable Gate Array) devices are the preferred choice for the implementation of reconfigurable computing platforms intended to accelerate processing in real-time systems. However, FPGAs vulnerability to hard and soft errors is a major weakness to robust configurable system design. In this paper, a novel Built-In Self-Healing (BISH) methodology, based on run-time self-reconfiguration, is proposed. A soft microprocessor core implemented in the FPGA is responsible for the management and execution of all the BISH procedures. Fault detection and diagnosis is followed by repairing actions, taking advantage of the dynamic reconfiguration features offered by new FPGA families. Meanwhile, modular redundancy assures that the system still works correctly.
