Only field multiplication and squaring (but not reduction) show a significant improvement. This is enabled on Power ISA >= 3.0. On a Power 9 CPU an average 10% performance improvement is seen (ECHDE: 14%, ECDSA sign: 6%, ECDSA verify 10%), compared to existing code. On an upcoming Power 10 CPU we see an average performance improvement of 26% (ECHDE: 38%, ECDSA sign: 16%, ECDSA verify 25%), compared to existing code.
