Notes:

  • This results present CPU performance compared to ARM Cortex M4
  • Higher values are better
Benchmark statistics:
  vexriscv picorv32 minerva cv32e40p serv lm32 mor1kx microwatt
speed geometric mean 66.0 17.0 11.0 30.0 1.0 50.0 54.0 42.0
speed geometric standard deviation 1.46 1.48 1.65 1.21 3.58 1.63 1.48 1.61

Notes:

  • Benchmark consists of multiple invidual tests
  • Higher geometric mean is better
  • Lower standard deviation is better, more consistent results
