Abstract
According to one general aspect, an apparatus may include a floating-point multiply-accumulate unit configured to generate a floating point result by either adding or subtracting three floating point operands: an addend, a product carry, and a product sum. The floating-point multiply-accumulate unit may include a close path adder. The close path adder may include an unincremented mantissa addition circuit configured to compute an unincremented mantissa result based upon the three floating point operands. The close path adder may also include an incremented mantissa addition circuit configured to, at least partially in parallel with the mantissa addition circuit, produce an incremented mantissa result. The close path adder may further include a selection circuit configured to produce a close path result by selecting between the unincremented mantissa result and the incremented mantissa result.
