Implementation of self-healing asynchronous circuits at the example of a video-processing algorithm

This paper presents a self-healing, asynchronous implementation of a small part of the hardware pre-processing to be used in the video processing unit of GAIA, a scientific mission of the European Space Agency (ESA). With the applied concept the circuit is able to detect permanent faults during runtime and to recover from them by an autonomous reconfiguration. The work describes how to transform a standard FSL circuit into a self-healing FSL design and presents first results of hardware experiments.
