Linpack Floating Point benchmark that runs as an Arduino sketch. (Yes, I know...)I wanted to generically measure Arduino Floating Point performance, this seemed like a reasonable(ish) way to do it. Runs with N=10, single precision, but produces sane looking results & residual. (89 Linpack kFLOPS on a Freetronics Eleven, ie Arduino Uno compatible…
