  FPMax implements four FPUs optimized for latency or throughput workloads in
two precisions, fabricated in 28nm UTBB FDSOI. Each unit's parameters, e.g
pipeline stages, booth encoding etc., were optimized to yield 1.42ns latency at
110GLOPS/W (SP) and 1.39ns latency at 36GFLOPS/W (DP). At 100% activity,
body-bias control improves the energy efficiency by about 20%; at 10% activity
this saving is almost 2x.
