Code Optimization for HVX
Generate optimized code for digital signal processing from blocks, System objects, and math operators using code replacement.
Qualcomm® Hexagon® processors require specific conditions to allow code replacement with the Hexagon Vector eXtension (HVX) for vector processors. You use this code replacement when generating C/C++ code from a model.
