Les objectifs de cette formation high-level design of software
The primary goal of this course is to give the participant the skills necessary to do high-level design of software for single-CPU real-time and embedded computer systems using a real-time operating system.

Participants

For architects, project managers and technical consultants who have responsibility for designing, structuring and implementing the software for real-time and embedded computer systems using an RTOS.

Pre-requisites

Course participants are expected to have thorough familiarity with at least one RTOS.

Pedagogic Methods

This is a very practical, results-oriented course that will provide knowledge and skills that can be applied immediately.

Program

Definitions / Real-Time Requirements

- Examine activities of high-level necessary for designing real-time and embedded systems.

- Definitions in real-time multitasking embedded application design and development.

- Fundamental issues.

- Brief review of several modern techniques for real-time and embedded software requirements specification.

- How to structure a system that must execute within strict deadline and resource limits.

- Requirements Analysis: Context Diagram and Usage Scenarios.

- Quick Overview of Entity-Relationship Diagrams, State Transition Diagrams and StateCharts.

- What You Get in an RTOS, and What You Don't Get.

Identifying Tasks and Objects
