MATLAB: Is Fixed Point Toolbox a requirement for Target Support Package TC2 even with a floating point digital signal controller

Question

The product requirements for Target Support Package TC2 includes Fixed Point Toolbox. I am using a board that is a floating point digital signal controller and wondering if I need Fixed Point Toolbox with it.

Answer 1

Even though digital floating point controller boards handle floating point numbers efficiently, they are still fixed-point core DSPs. Without the fixed-point toolbox one will not be able to take advantage of the DMC (Digital Motor Control) library and the IQmath library. Therefore motor control demos will not run without the Fixed Point toolbox.

You will be able to use the Target Support Package TC2 without the Fixed Point Toolbox but this will introduce severe limitations.
