Enable or disable type casting of input values for addition and subtraction operations
Preserve the types of input values during addition and subtraction operations and then convert the result to the result type.
Type cast input values in addition and subtraction operations to the result type before operating on the values. This setting produces numeric results that are typical of DSP processors.
CastBeforeSum property is related to
the FDATool setting for the quantization property Cast signals
before accum. as follows:
Some filter object types do not have the Cast
signals before accum. property. For such filter objects,
effectively off when HDL code is generated; it is not relevant to
Where the filter object. does have the Cast
signals before accum. property, the coder by default sets
the setting of Cast signals before accum. in
the filter object. This is visible in the GUI. If the you change the
setting of Cast signals before accum., the coder
updates the setting of Cast before sum.
However, by explicitly setting the
you can override the Cast signals before accum. setting
passed in from FDATool.
