Abstract
An apparatus that performs arithmetic logic and carry-lookahead logic in parallel on two N-nary operands, including saturating or unsaturating, signed or unsigned, addition or subtraction. The 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. Each selectable feature may be implemented singly, or in combination with other selectable features.
