System Objects Supported by Fixed-Point Converter App
Use the Fixed-Point Converter app to automatically propose and apply data types for commonly used system objects. The proposed data types are based on simulation data from the System object™.
Automated conversion is available for these DSP System Toolbox™ System Objects:
dsp.BiquadFilter(DSP System Toolbox)
dsp.FIRDecimator(DSP System Toolbox)
dsp.FIRInterpolator(DSP System Toolbox)
dsp.FIRFilter(DSP System Toolbox) (Direct Form and Direct Form Transposed only)
dsp.FIRRateConverter(DSP System Toolbox)
dsp.VariableFractionalDelay(DSP System Toolbox)
The Fixed-Point Converter app can display simulation minimum and maximum values, whole number information, and histogram data.
You cannot propose data types for these System objects based on static range data.
You must configure the System object to use
The app applies the proposed data types only if the input signal is floating point, not fixed-point.
The app treats scaled doubles as fixed-point. The scaled doubles workflow for System objects is the same as that for regular variables.
The app ignores the Default word length setting in the Settings menu. The app also ignores specified rounding and overflow modes. Data-type proposals are based on the settings of the System object.
