常量乘法器优化
R2026b通过使用正则有符号数 (CSD) 方法将常量乘法器转换为移位相加来优化面积
通过使用正则有符号数 (CSD) 方法将常量乘法器转换为移位相加，执行设计级面积优化。乘法器常量（例如，在增益因子或滤波器系数中）的 CSD 表示可显著减少硬件实现的面积。

Generate HDL Code from MATLAB Functions That Use Automated Lookup Table Generation
Generate HDL code from a floating-point MATLAB® design that is not ready for code generation. Use the fixed-point conversion process by using the float2fixed setting with the codegen function to generate a lookup table based MATLAB function replacement. Use the new MATLAB replacement function to generate the HDL code.
