    Hi,

    IQmath Library is collection of highly optimized and high precision mathematical functions for C/C++ programmers to seamlessly port a floating-point algorithm into fixed point code on TMS320C28x devices. It is required when FPU hardware support is not available on the device.

    FPU Fast Run Time Support (FASTRTS) Library is a collection of optimized math routines written for C2000 devices that utilizes FPU hardware on the device

    To enable FPU, right click and open project properties, go to Compiler options and enable fpu32 flag as shown below :
