Real-Time Windows Target
Run Simulink models in real time on Microsoft Windows PCs
Real-Time Windows Target™ provides a real-time engine for executing Simulink® models on a Microsoft® Windows® PC and blocks that connect to a range of I/O boards. It enables you to create and control a real-time system for rapid prototyping or hardware-in-the-loop simulation.
Real-Time Windows Target supports two Simulink simulation modes: normal mode, for simple real-time operation with access to I/O devices, and external mode, for higher real-time performance (with Simulink Coder™).
