Open the CIPO recordAbstract From the Canadian patent
A plurality of electronically reconfigurable gale array (ERCGA) logic chips are interconnected via a reconfigurable interconnect and electronic representations of large digital networks are converted to take temporary actual operating hardware form on the interconnected chips. The reconfigurable interconnect permits the digital network realized on the interconnected chips to be changed at will making the system well, suited for a variety of purposes including simulation prototyping, execution and, computing. The reconfigurable interconnect may comprise a partial crossbar that is formed of ERCGA chips dedicated to interconnection functions wherein each such, interconnect ERCGA is connected …

Why it's free to use
- Filed September 11, 1990 and granted January 19, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 11, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 11, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
