Abstract |
This paper presents a fault-tolerant duplex architecture to build a high-reliability microcontroller using commercial VLSI processors. The architecture supports fail-silence under all single-failure situations and facilitates recovery from transient failures. The paper implements the duplex architecture using two Motorola MC68360 processors and evaluates its fault tolerance in a real application environment. |
