RTI-MP

以图形方式设置多处理器和多核结构

Real-Time Interface (RTI-MP) 的多处理器选项支持基于 dSPACE PHS 硬件的多处理器和多核系统,有助于增强实时仿真的性能。

应用领域

Real-Time Interface (RTI-MP) 的多处理器选项支持基于 dSPACE PHS 硬件的多处理器和多核系统,有助于增强实时仿真的性能。它可帮助您设置多处理器网络,包括通信信道。多核应用与多处理器应用采用相同的配置方式。

使用 RTI-MP

RTI-MP 让您可以分割系统模型,然后通过简单的拖放操作将模型组件分配到处理器或内核。每个处理器子模型都可以单独调节以获得最佳性能,包括调节步长、积分算法及触发条件等。确定规格之后,只需要点击一次鼠标便能在处理器板上实施您的模型。构建程序也可以在脚本的帮助下自动进行。

主要优点

RTI-MP 能轻松完成以下任务:

  • 分割系统以优化处理器负载
  • 定义处理器之间的信道
  • 为多个处理器或内核组成的网络生成通信代码

可以在Simulink中设计系统动力学。
