KV4x: Enabling FPU

Hi,

I have many fixed point calculations that need to be calculated quickly in a task. I use the MKV46F128VLL16.

How can I enable the FPU?

Thank you very much.

Thank you for your help!

I am actually using Microsoft Visual Studio 2015 with the IAR Compiler. Do you know how I enable the FPU in this kind of toolchain?

It's the same procedure.
