The Embedded Coder® product extends the MATLAB® Coder™ product with capabilities that you can use for embedded software development. You can generate code that has the clarity and efficiency of professional handwritten code. For example, you can:
Generate code that is compact and fast, which is essential for real-time simulators, on-target rapid prototyping boards, microprocessors used in mass production, and embedded systems.
Customize the appearance of generated code.
Optimize generated code for application-specific requirements.
Enable tracing options that help you to verify the generated code.
The Embedded Coder product extends the MATLAB Coder product with the following options and optimizations for C/C++ code generation.
