A device may receive a floating-point function. The floating-point function may be a function described in a programming language that uses floating-point representation. The device may determine that fixed-point program code, associated with the floating-point function, is to be generated. The device may determine that the floating-point function is to be replaced with a replacement construct before the fixed-point program code is generated. The replacement construct may be described in the programming language and may be capable of conversion from the floating-point representation to a fixed-point representation. The device may determine parameters associated with generating the replacement construct. The parameters may be determined based on an evaluation of the floating-point function. The device may generate the replacement construct based on the parameters. The device may replace the floating-point function with the replacement construct. The device may generate the fixed-point program code based on the replacement construct.

Automatic replacement of a floating-point function to facilitate fixed-point program code generation

A device may receive input code that includes one or more input objects. The input code may be used in connection with generation of output code. The output code, when generated, may include one or more output objects, corresponding to and different than the one or more input objects. The device may receive or determine conversion information identifying a conversion operation to perform to generate the one or more output objects based on the one or more input objects. The conversion information may be received separately from the input code. The device may generate, based on the conversion information and the input code, an intermediate representation. The intermediate representation may include one or more annotations corresponding to the one or more input objects and defining the conversion operation. The device may compile, based on the intermediate representation, the output code. The device may execute or provide the output code.

Data type reassignment

A method and system for enabling a designer to more easily convert a model of a dynamic system instantiated using floating-point representation such as has been created in a high level design language to fixed-point code suitable for execution in a programmable processor or logic array.
