Thank you for trying C28x Software Collateral. 
Fixed Point MATH Library is installed in C:\TIDCS\C28\DSP_TBOX\QMATH directory.


Fixed point math library (QMATH) contains math/trigonometric routines that are developed 
as an easy-to-use library, which has to be linked to the user抯 application. 
The following table summarizes the set of functions that are defined in this library.
