Hi , i just compiled for st429 with the matherp last code (little change).
Here just the frequency adjusted and put it on a st429 disco board.

ABC 800 single precision 0.9 1.8 6.0 5.9 6.3 11.6 19.6 2.9
ABC 800 double precision 1.2 2.2 10.0 10.6 11.0 17.8 26.4 14.4

Maximite with line Nos 0.016 0.131 0.193 0.194 0.245 0.393 0.582 0.241
Maximite without line Nos 0.016 0.111 0.173 0.173 0.192 0.336 0.525 0.220
MicroMite 40MHz 0.028 0.18 0.285 0.289 0.644 0.892 1.346 0.376
MicroMite 48MHz 0.023 0.15 0.237 0.24 0.536 0.744 1.121 0.313

st429 180Mhz 0.012 0.073 0.117 0.125 0.207 0.315 0.497 0.162


Now , why is it not faster ? ... he he ...
The FPU is not active , no sdram , dma2d ... nothing , just like the st407 for this
test

Cheers.

Theory is when we know everything but nothing work ...
Practice is when everything work but no one know why ;)
