Code Optimization for QHL

Generate optimized code for Qualcomm^® Hexagon^® library using code replacement

Generate optimized code for digital signal processing from blocks, System objects, math functions, and math operators using code replacement.

Qualcomm Hexagon processors require specific conditions to allow code replacement with the Qualcomm Hexagon library (QHL for scalar processors). You use this code replacement when generating C/C++ code from a model.
