A WSI approach towards defect/fault-tolerant reconfigurable serial systems

A superchip for realizing ultra-large-scale integrated (ULSI) systems based on a wafer-scale integrated (WSI) circuit concept, which incorporates defect/fault tolerance and system reconfiguration, is introduced. The key features of the central architectural component, a large crossbar switch matrix, are described. A prototype has been fabricated in silicon technology. Hypothetical processor examples demonstrate the power of the superchip approach, and design/performance figures are discussed.<
