  • C2000 IQN to Float block


This block converts an IQ input to an equivalent floating-point number. The output is a single floating-point number.


The implementation of this block does not call the corresponding Texas Instruments library function during code generation. The TI function uses a global Q setting and the MathWorks® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.


For detailed information on the IQmath library, see the user's guide for the C28x IQmath Library - A Virtual Floating Point Engine, Literature Number SPRC087, available at the Texas Instruments Web site. The user's guide is included in the zip file download that also contains the IQmath library (registration required).
