ABSTRACT:
The absolute difference of two signed or unsigned integer numbers (A, B) is calculated in one instruction cycle by bit-complementing the B operand, summing the A and bit-complemented B operands to obtain an intermediate result, detecting whether the intermediate result overflows, then either incrementing the intermediate result or bit-complementing the intermediate result as appropriate. The B operand is bit-complemented by a first inverter circuit (302). The A and bit-complemented B operands are summed in an adder (304) that provides a sum and sum-plus-one output. The sum output is bit-complemented by a second inverter circuit (306). A multiplexer (310) under the control of a control circuit (308) selects one of the bit-complemented sum output and sum-plus-one output, based on inspection of the most significant bits of the A operand, B operand, and sum output, a carry-out bit from the sum output, and a mode signal indicative of whether the operands are signed or unsigned values.
