Other Parts Discussed in Thread: TMS320F2812, CONTROLSUITE, TMS320F28030

I have following polynomial equation to implement with TMS320F2812

X = - 32 * (10 ^ -8) *( Y ^ 3) + 4 * (10 ^ -3) * Y ^ 2 - 0.3 Y + 92.007

Please suggest if any specific library is to be added to imeplemnt this equation.

Example linker options and .cmd file if provided will be highly appreciated.

Adinath,

The F2812 device is a fixed point device, so I would recommend you implement your polynomial using IQmath. You can find IQmath as well as documentation and examples for it in controlSUITE in:

C:\TI\controlSUITE\libs\math\IQmath

assuming you installed controlSUITE in the default location.

Thanks Trey.

I will try the same and let you know the results.

Is it applicable for TMS320F28030/35?

Yes the F2803x devices are also fixed point so IQmath will be needed to emulate floating point.
