针对 QHL 的代码优化
R2026b使用代码替换，从模块、System object、数学函数和数学运算符生成针对数字信号处理的优化代码。
Qualcomm Hexagon 处理器需要满足特定条件才能使用 Qualcomm Hexagon Library（适用于标量处理器的 QHL）进行代码替换。当从模型中生成 C/C++ 代码时，您可以使用以下代码替换。
模块
 | QHL IIR Interpolator | Interpolate signals using cascaded biquad IIR filter optimized for QHL (自 R2026b 起) |
 | Sqrt | Compute square root of fixed-point signal with QHL-compatible scaling (自 R2026b 起) |
对象
hexagon.IIRInterpolator | Interpolate signals using cascaded biquad IIR filter optimized for QHL (自 R2026b 起) |
