Abstract :
We present an adder/substractor and a multiplier for single precision floating point numbers in IEEE-754 format. They are fully synthesizable hardware descriptions in VHDL that are available for general and educational use. Each one is presented in a single cycle and pipelined implementation, suitable for high speed computing, with performance comparable to other available implementations. Precision for non-denormal multiplications is under ulp and for additions in ±1 LSB.
