Abstract From the Canadian patent

Arbitrary and complex Boolean functions can be evaluate at high speed and with a minimal amount of memory by evaluating the total derivatives of the subfunctions out of which any given Boolcan function is built the Boolean function, is then generated from its total derivative. The total derivative of any binary or two input Boolean function is defined by a method dependent only on the inputs and the partial derivatives of the subfunction. By combining the subfunctions in a binary tree, a Boolean function of any complexity can be built up. By using a binary tree structure in a processing circuit or memory organization the method is generalized, to accommodate all possible Boolean functions. …

Why it's free to use

  • Filed February 6, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 6, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 6, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
