Conversione da virgola mobile a virgola fissa
È possibile convertire gli algoritmi in virgola mobile in DSP System Toolbox™ in algoritmi in virgola fissa utilizzando questi strumenti:
Applicazione Fixed-Point Converter per gli algoritmi MATLAB®
Fixed-Point Tool (Fixed-Point Designer) per i modelli Simulink®
Queste due feature richiedono il prodotto Fixed-Point Designer™.
Per un elenco dei System object DSP System Toolbox che supportano la conversione da virgola mobile a virgola fissa, vedere System Objects Supported for Automated Fixed-Point Conversion. Per un elenco dei blocchi che supportano la Conversione iterativa in virgola fissa in Simulink (Fixed-Point Designer), vedere Simulink Blocks in DSP System Toolbox that Support Iterative Fixed-Point Conversion Workflow.
