Abstract
Some embodiments provide a configurable IC that includes several configurable logic circuits, where the logic circuits include several sets of associated configurable logic circuits. For each several sets of associated configurable logic circuits, the reconfigurable IC also includes a carry circuit for performing up to N carry operations sequentially, wherein N is greater than two.
