The following general limitations apply to the use of Fixed-Point Designer™ functions in generated code, with
quantizer objects are not
Word lengths greater than 128 bits are not supported.
You cannot change the
numerictype of a
fi variable after that variable has been created.
boolean value of the
DataType properties are not supported.
SumMode property settings other than
CastBeforeSum property must be set to
When you compile code containing
fi objects with nontrivial slope
and bias scaling, you may see different results in generated code than you achieve by
running the same code in MATLAB®.
To view a list of the Fixed-Point Designer functions that are supported for code acceleration or C/C++ code generation, refer to the Fixed-Point Designer category of these tables:
In these tables, a icon before the name of a function indicates that there are specific usage notes and limitations related to code acceleration or code generation for that function. To view these usage notes and limitations, in the corresponding reference page, scroll down to the Extended Capabilities section at the bottom and expand the C/C++ Code Generation section.
