Embedded Coder Capabilities for Code Generation from MATLAB Code

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.
