Hi people, I am working with this DSC f28355, use a floating point calculus.
My question is about the time in calculus, by example I have this:
numV=(T*vi_11); denV=vo_11;
calculo_toff=((float)numV)/((float)denV);
I put a debugger pins in oscilloscope and look the consumption time by DSC, the time is 5.32 us.
I wish if is posible any answer about this, This is the speed of calculus?

Hi Frank, I put my compiler options:
fpu32 activated:
library rts2800_fpu32.lib:
Is correct this configuration?
I have found any forum entry (below link) that discuss about this question, is vey interesting.
But I have a message when stop the debugger session, this is a track that anything don't work properly?
Message: fs_div28.inc does not exist.
I test only the multiplication, the time consumption is 60 ns (measured with the oscilloscope) is OK.
The division, the time consumption is 1.60 us, I put the code:
GpioDataRegs.GPASET.bit.GPIO2 = 1;
calculo_toff=((float)numV)/((float)denV);
GpioDataRegs.GPACLEAR.bit.GPIO2 = 1;
calculo_toff is declarated float, and numV, denV since Uint16.
