Abstract
An apparatus and method for performing saturating addition or subtraction on two signed or unsigned operands using N-NARY logic. The two operands may be selectably partitioned into 8-bit, 16-bit, 32-bit, or 64-bit operands. For multiple partitions, carry propagation is interrupted on partition boundaries so that partitions may be saturated independently.
