Abstract
A system is described capable of excising individual cells in an N-dimensional array and healing the array connectivity without manual intervention. Thus cells that fail can be deleted and the array remain viable, although possibly requiring re-synchronization procedures to be performed. The system allows either replacement of bad cells or bypassing of bad cells, with appropriate cost and operational differences. Both level sensitive and edge sensitive excision mechanisms are described and the consequences of each discussed. The invention applies to processor arrays with one cell per physical chip or many cells per chip, and handles uni-directional or bi-directional data flows, and is generally both interface independent and technology independent.
