Abstract
An array of processing element nodes are provided on a semiconductor wafer. A mixed redundancy approach is preferably employed wherein two spare core logic circuit modules 52, 58 are available for use at each node. Each spare core logic module can be connected to one of four different nodes. An H-net 94 interconnects adjacent nodes in such manner that faults in the circuit modules can be easily tested and repaired.
