Relation between fault tolerance and reconfiguration in cellular systems

Recently, hardware researchers have promptly begun to investigate alternative computational principles to the conventional ones. The main signs of these principles are inspiration in biology and their direct hardware implementation. Evolvable hardware, cellular computing or embryonic electronics are the most important examples. This paper describes different approaches to configuration, reconfiguration and fault tolerance implementation of two-dimensional cellular system. Simplicity of the cell, vast parallelism, and the connection locality are considered as the design restrictions.
