Konvertieren von Gleitkomma zu Festkomma

Konvertieren von Algorithmen und Modellen

Mithilfe der folgenden Tools können Sie Gleitkomma-Algorithmen in DSP System Toolbox™ in Festkomma-Algorithmen konvertieren:

Diese zwei Funktionen erfordern das Produkt Fixed-Point Designer™.

Eine Liste der DSP System Toolbox System objects, die eine Konvertierung von Gleitkomma zu Festkomma unterstützen, finden Sie unter System Objects Supported by Fixed-Point Converter App. Eine Liste der Blöcke, die Iterative Fixed-Point Conversion in Simulink (Fixed-Point Designer) unterstützen, finden Sie unter Simulink Blocks in DSP System Toolbox that Support Iterative Fixed-Point Conversion Workflow.
