Claim One:
1. A programmable integrated circuit having one or more cascaded-function generating modules, each module comprising: (a) input means for receiving a plurality of input signals including first-level input signals; (b) first look-up table means for storing a first plurality of N bits that encode a programably-defined first function-defining pattern; (c) second look-up table means for storing a second plurality of M bits that encode a programably-defined second function-defining pattern; (d) first function defining means, operatively coupled to the input means and to the first look-up table means, for defining a plurality of first function signals from a combination of the first-level input signals and plural ones of the bits stored in the first look-up table means; and (e) second function defining means, operatively coupled to the second look-up table means and to the first function defining means, for generating a cascaded function signal from a combination of the first function signals and plural ones of the bits stored in the second look-up table means.
