Generate Target Optimizations Within Algorithm Code

Some application components are hardware-specific and cannot simulate on a host system. For example, consider a component that includes pragmas and assembly code for enabling hardware instructions for saturate on add operations or a Fast Fourier Transform (FFT) function.

The following table lists integration options to customize generated algorithm code with target-specific optimizations.

Note

Solutions marked with EC only require an Embedded Coder^® license.

You want to control how code generation technology declares, stores, and represents signals, tunable parameters, block states, and data objects in generated code	EC only—Design (create) and apply custom storage classes	openExample ("ImportStruct") Create Storage Classes by Using the Custom Storage Class Designer Configure Model Data Interface for C Code Generation Organize Parameter Data into a Structure by Using Struct Storage Class

Note

To simulate an algorithm that includes target-specific elements in a host environment, you must create code that is equivalent to the target code and can run in the host environment.
