RTOS Application: Development of Runtime Architectures for Embedded and Real-Time Systems

• Embedded and Real-time Software Development Procedure
  • From the idea to the final runtime architecture
  • Runtime architecture patterns and their use for concrete tasks
  • Transformation of an existing software architecture without operating system to an architecture with operating system, with optimized utilization of the OS mechanisms
  • Introduction and comparison of different runtime architecture concepts - with and without operating system
  • Predictability and calculability of various runtime architecture concepts
  • Guidelines for selecting the right runtime concept
  • Practical example: Measurement device application
  • Exercise: Development of a suitable runtime architecture for a real embedded system based on drawn up textual requirements and a software architecture
• Multicore and Multiprocessor Aspects
  • Hardware and software architectures
  • Task assignment
  • Possible operating system applications
  • Virtualization and hypervisor
  • Interrupt and driver concepts
  • Important design aspects
• Documentation and Communication
  • Suitable modeling formats for a runtime architecture
  • Excerpts from UML (Unified Modeling Language)
  • Practical tips
  • Exercise: Using UML notations and diagrams for modeling the runtime architecture
• Operating System Abstraction Layer OSAL
  • Description of benefits, advantages and disadvantages
  • Programming
  • Practical example with FreeRTOSTM
• Operating System Selection Guidelines and Product Overview
  • Operating system selection guidelines
  • Practical tip: Operating system comparison
  • Current product overview for embedded software
  • Checklist with important selection criteria
• Practical Exercises
  • Development and documentation of a runtime architecture for a convenient electric motor control application using operating system mechanisms
  • The exercises are performed using Enterprise Architect (Sparx Systems) or paper and pencil
• MicroConsult Plus:
  • All participants have the following options to further use their exercises and the solutions developed by MicroConsult from this workshop:
  • You take the files with you on a free USB stick provided by MicroConsult, or
  • You e-mail the files to your account, or
  • You get access to file download on request.
  • For the measurement device application, you get the program code and a UML model as well as a UML model for the electric motor application.
  • You get a tool and software component overview including a current operating system overview
  • You also get a checklist with operating system selection criteria.
  • You get helpful notation overviews for UML (Unified Modeling Language) and SysML (Systems Modeling Language) in DIN-A3 format.

Lernziele

• After the RTOS training, you can develop new software runtime architectures and maintain existing ones using sophisticated real-time operating systems (RTOS) - independent of the concrete real-time system product. You are able to document and communicate software runtime architectures and make an informed choice about operating systems.

Zielgruppe

• The RTOS training addresses programmers, software developers, software designers and software architects who are using or are planning to use a real-time operating system in their embedded software application.

Voraussetzungen

• Basic knowledge of microcontrollers; knowledge of C programming and typical operating system mechanisms and their functions.
