IQmath vs. floating point

Other Parts Discussed in Thread: TMS320F28335, CONTROLSUITE

Hello,

I decided to realize my project on the TMS320F28335 controler. In controlSUITE there are 2 solutions concerning real FFTs on this device: one realized with support of IQmath-library and one realized with the floating point capabilities of the F28335. You can find them under the dsp-library folder. My question is, where are the benefits using IQmath on a floating-point-controler.

Thank you for any hint,

Regards,

Ludger

    Hi Ludger,

    The basic motive of using iQmath library is when you have a non-floating point/fixed point controller; and if you want to improve the computation performance. When you already have a floating point controller F28335 there's no need of iQmath, instead you can use a library called as fastRTS for quicker computations.
