RELIABLE FAULT TOLERANT MULTI-CORE SYSTEM: A SURVEY

Abstract

ARM Processor is a core used in 100’s of billion of real-time Embedded System which contain
Electronics with less area overhead, low power consumption, reduced cost and portable with high
computation. To carry the user experience in the home, and office over the car such embedded
solution based on multi-core platforms are used in diverse application domain like aerospace,
industrial automotive, Smartphone, Tablets, Medical, Audio Video player to provide fail safe
operation with consumer comfortability. This paper focuses on survey of various faults tolerant
techniques for ensuring low overhead to protect processor and program execution flow which
improves the reliability of the system. Hardware implemented fault tolerant techniques inevitably add
resource overhead while Software implemented fault tolerant technique add runtime overhead. The
future scope of this paper provides a trade-off between resource overhead and runtime overhead to
improve fault coverage.
