Open the CIPO recordAbstract From the Canadian patent
This invention relates to the generation of number theory mappings and their application to the addressing of matrix structures through the provision of an address generator which is optimised for the general task of applying "on the fly" number theory mappings to matrix operands as they are fetched from memory. The address generator (10) comprises a set of six matrix descriptor storage registers (11-16), a finite state machine controller (17) a, decrementer (18) for cyclically decrementing a matrix size descriptor (12), an additional decrementer (19) for cyclically decrementing the matrix size descriptor (11), a finite difference engine (20) which adds one of two matrix difference …

Why it's free to use
- Filed June 27, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 27, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
