Dynamic reconfiguration for fault tolerance for critical, real-time processor arrays
Molisa Derk, Linda S. DeBrunner · 2002
Real-time digital signal processing for critical applications demands that rapid successful reconfiguration techniques be employed to increase fault tolerance. To meet this need, we introduce and demonstrate a local area reconfiguration algorithm for a rectangular processor array that is very efficient, does not require a host processor, and will successfully reconfigure for a fault anywhere in the local area if there is an available spare. Further, if all the spares in a local area are used, areas can be combined in a software controlled process, preventing a system failure.>
