Floating-Point to Fixed-Point Conversion
You can convert floating-point algorithms in DSP System Toolbox™ to fixed-point using these tools:
The
codegen(MATLAB Coder) orfiaccel(Fixed-Point Designer) function for MATLAB® algorithmsFixed-Point Tool (Fixed-Point Designer) for Simulink® models
These two features require the Fixed-Point Designer™ product.
For a list of DSP System Toolbox System objects that support floating-point to fixed-point conversion, see System Objects Supported for Automated Fixed-Point Conversion. For a list of blocks that support the Iterative Fixed-Point Conversion in Simulink (Fixed-Point Designer), see Simulink Blocks in DSP System Toolbox that Support Iterative Fixed-Point Conversion Workflow.
