Using the above calculations, this suggests the STM32F412 is running at 12.79 MFLOPS, or 33 clock cycles per iteration. Adding the `-ffast-math` option to `rules.mk` did not change this number. The datasheet suggests a typical current consumption of 22.7 mA at 84 MHz (with all peripherals on); at 3.3 VDC, this equates to 74.9 mW, or 0.171 GFlops/W.
