Target dei processori multicore

Modellare l'esecuzione simultanea di sistemi progettati per l'implementazione su un sistema multicore o FPGA

La programmazione multicore, o modellazione per l’esecuzione simultanea, aiuta a creare sistemi concomitanti da distribuire su processori multicore e sistemi multiprocessore. Esempi di tali sistemi sono i sistemi di elaborazione del segnale e di controllo degli impianti. Le tecniche di partizione e mappatura di Simulink^® aiutano a superare le sfide più comuni nella progettazione di sistemi per l'esecuzione simultanea.

La figura mostra un esempio di sistema con più funzioni progettato per essere eseguito su un sistema multiprocessore basato su CPU e FPGA. Il sistema è suddiviso in più componenti che vengono mappati sull’unità di pianificazione della CPU o sull'FPGA.

Per scoprire i fondamenti della programmazione multicore, vedere Concepts in Multicore Programming. Per informazioni su come progettare sistemi per l'esecuzione simultanea in Simulink, vedere Multicore Programming with Simulink.
