  • xPCTargetManual
    xPC Target 工具箱使你可以在 Simulink 的框图中加入 I/O 方块图,并用 RTW 产生代码,最后下载到另一个运行 xPC Target 实时内核的 PC 机上。对于控制和 DSP 系统来说 xPC Target 是理想的快速原型和硬件在回路测试工具,它可以使你在一台标准的 PC 机上运行实时模型。如果附加 xPC Target 嵌入模块选项,你可以把你的实时嵌入式系统放入到一台微机上,应用于生产、数据采集、标定和测试应用程序等过程中。 (xPC Target toolbox allows you to add in the Simulink block diagram of the I/O block diagram, and use RTW generated code, and finally downloaded to another running xPC Target real-time kernel of the PC machine. For the control and DSP systems is ideal for the xPC Target rapid prototyping and hardware in the loop testing tool that allows you to a standard PC, running real-time model. If the additional xPC Target Embedded Module option, you can put your real-time embedded systems to a microcomputer applied to the production, data acquisition, calibration and test applications such as process. )
