Optimisation automatisée des performances

Analyser le modèle pour détecter les conditions et paramètres inefficaces et augmenter automatiquement la vitesse de simulation avec Performance Advisor

Performance Advisor peut rechercher dans votre modèle les conditions et les paramètres susceptibles de ralentir les simulations. Il peut recommander des optimisations de modélisation, les implémenter automatiquement et exécuter des simulations en mode Accelerator à votre place. Pour plus d’informations, consultez Improve Simulation Performance Using Performance Advisor.

Use Hardware Acceleration to Speed Up Simulation for Object Detection

Use hardware acceleration to speed up a Simulink® model simulation for object detection. You can use Performance Advisor to compare simulation speeds and select an appropriate level for hardware acceleration. Hardware acceleration is achieved by leveraging single instruction, multiple data (SIMD) in simulation targets. All processors that support Simulink simulation have SIMD instructions. For more information, see Hardware acceleration and SIMD Code Generation (DSP System Toolbox).
