arduino_fbench

fbench port to Arduino (compatible with LGT8Fx)

This is a quick and dirty port of the John Walker's Floating Point Benchmark to Arduino.

This port is mainly intended to compare performances between ATmega328p and LGT8F328p, and between different compilation optimization levels.

optimization LGT8F328p @ 32MHz LGT8F328p @ 16MHz ATmega328p @ 16MHz
Os 4.670s
O0 5.105s
O1 4.657s
O2 4.651s
