https://devzone.nordicsemi.com/f/nordic-q-a/3932/floating-point-operations-per-secondHello, now anybody how many floating point operations per second are possible with the NRF51422?

I think when i now the cycles than its possible to calculate the time with help of the Assembly code</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14146?ContentTypeID=1Fri, 26 Sep 2014 13:24:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0ff5aa16-7219-4d43-8e75-761220a8a280Asbj&#248;rn<p>The nRF51422 is based on a standard ARM Cortex M0 implementation so the best number I would be able to give you with regard to <a href="http://en.wikipedia.org/wiki/Instructions_per_second">processing power is the number stated on the wikipedia table about instructions per second.</a></p><div style="clear:both;"></div>
