시간 기반 스케줄링
시간 기반 스케줄링에 의존하는 알고리즘을 지원하고 이에 필요한 코드를 생성하도록 모델을 설계합니다. 연속 블록과 이산 블록의 사용법을 평가합니다. 하나 이상의 샘플 레이트에서 실행되는 모델에서는 고정 스텝 솔버를 사용하십시오. 싱글태스킹 실행 모드와 멀티태스킹 실행 모드 중에서 선택하십시오. 모델 내에서 샘플 레이트 변환을 식별하고 처리합니다.
도움말 항목
- Time-Based Scheduling and Code Generation
Consider continuous and discrete block usage, sample times, rate transitions for multirate models, discretization, and choosing between single-tasking mode and multitasking mode when designing models intended for code generation.
- Periodic and Aperiodic Function Interfaces
Generate callable entry-point functions for the algorithm represented by a top model.
- Configure Time-Based Scheduling
Configure the solver type, solver, fixed-step size, periodic sample time constraints, and solver diagnostics for code generation.
- Execution of Code Generated from a Model
Execute code generated from single-tasking and multitasking models for rapid-prototyping and embedded system run-time environments.
- Tasking Modes and Execution Order
Example that shows task execution order for blocks in a model when configured for single-tasking versus multitasking execution.

Single-Rate Modeling (Bare Board, No OS)

Multirate Modeling in Single-Tasking Mode (Bare Board, No OS)
The code generated for a multirate discrete-time model configured for single-tasking on a bare-board target (one with no operating system).
Multirate Modeling in Multitasking Mode (Bare Board, No OS)
The code generated for a multirate discrete-time model configured for a multitasking bare-board target (one with no operating system).
Multirate Modeling in Multitasking Mode (VxWorks® OS)
Generates code for a multirate discrete-time model configured for a multitasking operating system target (VxWorks®). The model contains two sample times. Inport block 1 and Inport block 2 specify 1-second and 2-second sample times, respectively, which are enforced by the setting of model configuration parameter Periodic sample time constraint. The solver is set for multitasking operation, which means a Rate Transition block is required to ensure that data integrity is enforced when the 1-second task preempts the 2-second task. Simulink® and the code generator enforce proper rate transitions. This model specifies an explicit Rate Transition block. Alternatively, you can instruct Simulink® to insert this block for you by setting model configuration parameter Automatically handle rate transition for data transfer.
