Conditions for Code Replacement of Math Functions with QHL

Each math function that can be used with the Embedded Coder^® Support Package for Qualcomm^® Hexagon^® Processors requires specific conditions to allow code replacement by using the Qualcomm Hexagon Library (QHL). You use this code replacement when generating C/C++ code from a model or from MATLAB^® code.

If you do not meet the specific requirements, then the generated C/C++ code runs on the Qualcomm Hexagon Processors. However, this generated code does not use library support.

The library supports these Math functions only when you set specific properties, as indicated in this table:
