Block Replacement
Define code replacement mappings for Simulink® blocks
Replace the code generated from specific Simulink blocks with custom implementation code. For computationally intensive blocks, you can replace default generated code with custom implementations such as library functions that are optimized for your target hardware.

Topics
- Block Replacement for Code OptimizationCustomize how and when the code generator replaces C/C++ code that it generates for Simulink blocks. 
- Replace Code Generated from Discrete FIR Filter BlocksDefine code replacement mappings that replace code generated from filter blocks. 
- Use Derived Data in Replacement Code ImplementationsDefine how implementation code uses data derived from block inputs, outputs, and parameters.
