8. One or more non-transitory computer-readable media holding executable instructions that when executed on a processing device replaces operators in model code, the media holding one or more instructions for: identifying a pattern in model code, where: the model code is associated with a graphical model having executable semantics, the pattern is associated with an operator in the model code, and the operator performs operations when the model code is executed; selecting, for the identified pattern, a hardware specific function that performs an operation equivalent to a respective operation performed by the operator in the model code; replacing the operator in the model code with the selected hardware specific function, wherein conceptual arguments of the selected hardware specific function match argument properties of the operator, and wherein argument properties of the selected hardware specific function do not exactly match function properties of the operator; and storing the model code.

The media of claim 8 , wherein selecting the hardware specific function is based on the argument properties or data type of the operator in the model code.
