Fixed-Point Code Generation in MATLAB

Fixed-point C-code generation using MATLAB® Coder™

To generate code, you must have the MATLAB Coder product. For information on code generation, see the MATLAB Coder documentation.

Topics

Ways to Generate Code

Discusses using Fixed-Point Designer™ software with code generation.

Workflow for Fixed-Point Code Acceleration and Generation

Describes the steps required for preparing MATLAB code and converting it to a MEX function.

Functions Supported for Code Acceleration or C Code Generation

Lists the Fixed-Point Designer features supported by code generation from MATLAB.

Code Generation with MATLAB Coder

Introduces you to the MATLAB Coder product.

Code Generation for Constants in Structures and Arrays

Sometimes the code generator does not recognize constant structure fields or array elements.

Code Generation with MATLAB Function Block

Introduces you to the MATLAB Function block.

Generate Fixed-Point FIR Code Using MATLAB Function Block

Create and generate code for a fixed-point, low-pass, direct form FIR filter.

Avoid Multiword Operations in Generated Code

This example shows how to avoid multiword operations in generated code by using the accumpos function instead of simple addition in your MATLAB algorithm.

Find Potential Data Type Issues in Generated Code

Highlight potential data type issues in report.

Troubleshooting

Fix Run-Time Stack Overflows

If your C compiler reports a run-time stack overflow, set the value of the maximum stack usage parameter to be less than the available stack size.

Tips for Making Generated Code More Efficient

Describes techniques which can be used to make generated code more efficient.

Supported Data Types
