Publications#

Here you find a summary of research publications on error detection-based fault-tolerance (EDFT) for sequential circuits like processors:

  • The idea came up when I was working on the satellite computer described in [1].

  • [2] introduces the idea of EDFT in general.

  • [3] I give a first insight to the performance of EDFT using parity-based error detection by comparing our approach with LTMR analytically. Synthesis results using a real circuit is gathered in [4].

  • [5] tries to improve the timing of EDFT using pipelining.

  • [6] is an extended version of [4] and provides a more detailed specification and fault tolerance analysis of transaction-based processing.

Finally [7] compiles my research work. Dissertation slides includes key diagrams and results of my dissertation.
