Abstract: A bio-inspired fault tolerant approach for Sobel operator was described in this paper. I3y imitating four bio- logical principles, namely, match-based recognition in protein sorting, substitution among homogeneous cells, differentia- lion of stem cells,and conversion between heterogeneous cells, we designed the architecture of electronic tissue(eTis- sue) , which supports hierarchical self-healing. We then implemented the eTissue architecture which is specific to Sobel operator by programming with MPI. Our fault injection experiments prove the feasibility of this fault tolerant approach.
