The ELSA wafer scale integration project

Outlines some of the technology, successful and unsuccessful, of part of a large European project in wafer scale integration (WSI). The work described is an attempt to build a 64 by 64 array processor on a 4-in wafer. Such a processor would have a computing power in excess of 10 billion operations per second. A test chip and a demonstration system, which achieves such a processing power, is also described.<
