Programmable logic block with carry chains providing lookahead functions of different lengths

A programmable logic block provides N-bit and M-bit (e.g., (N/2)-bit) lookahead functionality for carry chains traversing the logic block, N and M being integers greater than one. An exemplary programmable logic block includes four carry multiplexers that together form a 4-bit lookahead carry chain....
