Abstract

A programmable look-up-table (LUT) structure adapted for carry logic incrementer implementation in an integrated circuit, comprising: three or more data inputs and a carry-in input, said data inputs comprised of consecutive bits in a data string, said carry-in comprised of the increment value to the least order bit of said data string; and three or more data outputs and a carry-out output, said data outputs comprised of the incremented values of said data inputs, and said carry-out resulting from the incremented value of the highest order bit of said data inputs; wherein, said three or more data outputs are computed in a single carry computation stage within the LUT structure.
