优化性能

针对特定目的优化性能、加快仿真速度以及设计高效模型

高性能的 Simulink^® 模型可以快速编译和进行仿真。您可以利用 Simulink 提供的方法加快模型仿真速度。

提高仿真性能的第一步，就是使用性能顾问。性能顾问可以找出可能会减慢仿真速度的条件。该工具可以自动对模型进行更改以解决这些条件，您也可以手动查看和应用建议的更改。

Introduction to Accelerating Models

Simulink® Accelerator™ speeds up the execution of your model, by creating and compiling C code. This C code takes the place of the interpretive code that Simulink uses when in Normal mode (that is, when Simulink® is not in Accelerator mode). Simulink Accelerator generates the C code from the Simulink model and invokes the MATLAB® mex function to compile and dynamically link the generated code to Simulink. This code generation and compilation process happens the first time you accelerate the model and any time the model changes are significant enough to require re-generation (for example, the addition of a block).

Implement an FFT on a Multicore Processor and an FPGA

Take advantage of a multicore processor target with FPGA acceleration by graphically partitioning a model. This example requires Simulink Coder™ to generate multi-threaded code and HDL Coder™ to generate HDL code. You cannot generate HDL code on Macintosh systems.
