Open the CIPO recordAbstract From the Canadian patent
A asynchronous digital system, an asynchronous data path circuit, an asynchronous digital signal processing circuit and anasynchronous digital signal processing method which, enables improved processing speed while maintaining high reliability are provided by dividing the overall chip into blocks with a specified area, forming the connection between the blocks by applying thereto a delay insensitive (DI) model or a quasi delay insensitive (QDI) model while forming each, block by applying thereto a scalable delay insensitive (SDI) model. In the SDI model, the system is configured using circuit components having a delay assumed during design in which if the specification states that a signal …

Why it's free to use
- Filed October 3, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 3, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 3, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
