Patent ID: 7605605

Claim:
A programmable logic structure for point-to-point local connections, comprising an output logic and routing cell multiplexer in a first means at a first level; and a first input logic and routing cell multiplexer in a second dedicated logic at a second level, the output logic and routing cell multiplexer in the first dedicated logic cell at the first level making a direct point-to-point connection to the first input logic and routing multiplexer cell in the second dedicated logic cell at the second level without routing the connection through a switch circuit; wherein the first dedicated logic cell comprises; a first logic and routing cell; and a second logic and routing cell coupled to the first logic and routing cell, the first logic and routing cells including: a first look-up table having a plurality of inputs for receiving a set of inputs and at least one output; a second look-up table having a plurality of inputs for receiving the set of inputs and at least one output; a third look-up table for receiving at least one input and generating at least one output; and a fourth-look-up table for receiving at least one input and generating at least one output; a logic having inputs coupled to the first, second, third, fourth look-up tables and generating at least one output.
