IQ math library usage

Hi all,

I am having some trouble with the IQmath library for enhancing code speed. I have a double PI controller inside an ISR triggered by an ADC interrupt. The SOC for the ADC happens every 12us.

If I have the controller self made with normal floating point multiply operations and data types it works fine. However, when I try to exchange the controller or its operations with blocks from the library IQmath, my code becomes slower and can no longer reach these 12us.

Is there something I am missing out here? I have no fixed point license, could that be causing any inconvenience?

Here a small extraction of the code. From here I am guessing the installation of the IQmath lib went OK.

Thanks for the help
