Speed-independent fused multiply-add unit as a coprocessor is represented. It purely conforms to IEEE 754 Standard. For minimization hardware and power consumption, a number of pipeline stages is reduced down to two. Wallace tree in the multiplier utilizes redundant self-timed code. Represented unit is developed on a base of standard 65-nm CMOS bulk process. It provides a performance up to 0.54 Gflops, and power consumption at level of 450 mW/Gflops
