Code Optimization for QHL
R2026bGenerate 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.
Blocks
 | QHL IIR Interpolator | Interpolate signals using cascaded biquad IIR filter optimized for QHL (Since R2026b) |
 | Sqrt | Compute square root of fixed-point signal with QHL-compatible scaling (Since R2026b) |
Objects
hexagon.IIRInterpolator | Interpolate signals using cascaded biquad IIR filter optimized for QHL (Since R2026b) |
