ABSTRACT:
A programmable logic device that provides an AND gate array connected to an OR gate array connected to a third logic level, a logic expander module. The module provides programmable selection of any of 16 one- and two-variable logic functiosn or any of 256 one-, two- and three-variable logic functions. In one embodiment, the invention uses logic function gates such as AND, OR, XOR and inverter gates to form the logic functions. In a second embodiment and a third embodiment, a look-up table and an array of pass transistors, respectively, are used to form the logic functions.
