Adaptive-logic trees for use in multilevel-circuit design

A logic tree employing only 2-input gates is described which is capable of mechanising any desired function of the variable set. The tree can therefore represent either a fixed relationship, or vary adaptively by adjusting the input parameters. It is shown that this structure can be used to derive economic multilevel representations of functions directly from the canonical form which require only 2-input gates. The design procedure can operate effectively with only a simple set of design rules.
