<p>Logic elements (20) for use in carry/borrow and comparator systems, which operate in accordance with the IMPLY logical relationship. Utilization of the IMPLY logical relationship overcomes the inherent complication of inversion so that it becomes an effective benefit, making possible uniform carry system layouts with uniform logic elements using a newly defined gate pair combination in general. The gate pair logic elements (20) provide a novel carry-propagate signal P which includes a redundant carry-generate signal G, thereby defining a novel carry-integrate signal I (Ao). The novel carry-integrate signal I (Ao) together with the carry-generate signal G (Bo) define a signal pair utilized in succeeding carry levels which are organized in a simplified fashion.</p> |
