Modeling and Analysis of Real Time and Embedded systems

Modeling and Analysis of Real Time and Embedded systems is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Modeling and Analysis of Real Time and Embedded systems rather than just read about it. In short: Modeling and Analysis of Real Time and Embedded systems also known as MARTE is the OMG standard for modeling real-time and embedded applications with UML2. Description The UML modeling language has been extended by the OMG consortium to support model-driven development of real-time and embedded application.

Key takeaways

Modeling and Analysis of Real Time and Embedded systems belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Modeling and Analysis of Real Time and Embedded systems to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Modeling and Analysis of Real Time and Embedded systems from memory before moving on to harder problems.

Reference excerpt

Modeling and Analysis of Real Time and Embedded systems also known as MARTE is the OMG standard for modeling real-time and embedded applications with UML2.

Description The UML modeling language has been extended by the OMG consortium to support model-driven development of real-time and embedded application. This extension has been defined via a UML2 profile called MARTE (Modeling and Analysis of Real-Time and Embedded systems). It consists mainly of four parts:

a core framework defining the basic concepts required to support real-time and embedded domain. a first specialization (refinement) of this core package to support pure modeling of applications (e.g. hardware and software platform modeling). a second specialization (refinement) of this core package to support quantitative analysis of UML2 models, specially schedulability and performance analysis. a last part gathering all the MARTE annexes such as the one defining a textual language for value specification within UML2 models, and the one conflating the standard MARTE model libraries dedicated to RT/E system modeling. The MARTE specification is publicly available on the OMG web site. Currently, two open-source tools are available for system modeling using the MARTE profile: Modelio provides an open source modeling environment for designing high level UML models using the MARTE profile, and also provides guidelines on the utilization of MARTE profile; while an open-source implementation based on Eclipse of the MARTE profile is available in Papyrus UML. This latter is running within the Eclipse UML2 plug-in and within the open-source tool for UML2 Papyrus.

Core The core part of MARTE is made of five chapters.

CoreElements; Non-Functional Properties: This chapter specifies some notations to define various kinds of values related to physical quantities: time, mass, energy; Time: This chapter defines a rich model of time that supports both the definition of physical and logical time properties;. It comes with a companion language called CCSL defined as an annex. Generic Resource Modeling: This chapter offers extensions required to model a general platform for executing real-time embedded applications; Allocation Modeling: Finally, this chapter defines a notion of allocation to allocate application elements onto the execution platforms. A specific attention has been given to maintain compatibility with SysML allocation mechanism.

Notes

Worked examples

Example 1 — a first encounter with Modeling and Analysis of Real Time and Embedded systems

Start with the simplest possible case. Write down what Modeling and Analysis of Real Time and Embedded systems claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Modeling and Analysis of Real Time and Embedded systems before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Modeling and Analysis of Real Time and Embedded systems ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Modeling and Analysis of Real Time and Embedded systems

In research: Modeling and Analysis of Real Time and Embedded systems appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Modeling and Analysis of Real Time and Embedded systems in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Modeling and Analysis of Real Time and Embedded systems is common in secondary-school and first-year university syllabi. It links to neighbouring topics Unified Modeling Language, Unified Modeling Language stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Modeling and Analysis of Real Time and Embedded systems outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
