A method and a device including, in one embodiment, a multiply array and at least one adder to perform a floating-point multiplication followed by an addition when operands are in floating-point format. The device is also configured to perform an integer multiplication followed by an accumulation when operands are in integer format. The device is further configured to perform a floating-point multiply-add or an integer multiply-accumulation in response to control signals. In another embodiment, the device contains an adder and the adder is capable of performing a floating-point addition and an integer accumulation. The adder is configured to be extra wide to reduce operand misalignment. Moreover, the device stalls the process in response to operand misalignment.
