Abstract
A logic circuit includes a first series of logic elements. Each logic element has a look-up table (LUT) and a dedicated adder to implement an arithmetic mode in the logic element. The logic circuit also includes a carry chain connecting the first series of logic element, and an initialization circuit connected to the carry chain to initialize the carry chain.
