应用程序和组件接口

设置应用程序和组件接口，以便与目标环境软件进行交互

应用程序和组件是代码单元，由代码生成器从顶层模型中生成。部署要在目标执行环境中使用的应用程序和组件。为了使代码生成器生成能够与目标环境服务交互的 C 或 C++ 代码，您必须通过使用以下各项的组合来使代码生成器了解服务接口要求：

顶层模型中的模型元素
在 Embedded Coder 字典中定义的代码接口配置（仅限 C 代码）
将模型元素与代码接口配置中定义的接口相关联的代码映射

生成的应用程序和组件代码通过这些生成的代码接口与目标环境服务进行交互：

目标软件（如调度器）可以调用的入口函数
对目标软件的函数调用，例如平台服务函数

Model Single-Core, Rate-Monotonic Multitasking Application

A model designed and configured for generating embedded system code intended to execute as an application in a single-core, multitasking target environment. The application algorithm is captured as a multirate top model that is configured for C data interface code generation. The model simulates and the generated code executes based on the model configuration and a rate monotonic scheduling algorithm.

Model Multicore Concurrent Tasking Application

A model designed and configured for generating embedded system code intended to execute as an application in a symmetric multicore, multitasking target environment. The application algorithm is captured as a multirate top model that is configured for C data interface code generation.

Generate Code for Atomic Subsystems

A model designed and configured for deploying embedded system component code that is generated from a model that is partitioned into multiple atomic subsystems. The subsystems execute at different rates. The multirate top model is configured for C data interface code generation. You integrate the generated source code for each subsystem with other code, including an external scheduler, that runs in a target environment.
