Designing software components for real-time applications

Thus, you can configure your project by implementing third-party compilers and tools. Initially, the Eclipse integrated development environment was created for Java applications, and now it is the most widely used solution by Java programmers.

A separate package — Eclipse IDE for Automotive Software Developers — contains tools and frameworks for quick and easy creation of embedded automotive software. A free and open-source IDE for Java 8 development, NetBeans is supported by a large community of developers and users. Developers in different areas use MATLAB to create user interfaces, implement algorithms, work with data plots, functions, matrices, graphs, etc.

The combination of MATLAB and Simulink is useful for embedded software developers, as it allows them to design and code an embedded system from prototyping to production. It provides a range of features and libraries that make the life of embedded programmers easier.

ARM Keil development tools provide a complete environment for creating embedded applications for the widest range of ARM-based devices.

Abstract - Add to MetaCart Abstract — Component middleware technologies are increasingly used to assembly large-scale distributed real-time and embedded DRE systems composed from many individual components. Without effective optimization techniques, therefore, a large class of DRE systems with stringent footprint requirements may not be able to use component middleware effectively.

This paper provides four contributions to the study of optimization techniques for component-based DRE systems. First, we describe the challenges in designing component-based DRE systems and identify the sources of overhead in typical componentbased.

Advances in support for easy program development across heterogeneous devices, by a broad developer base with a range of expertise and backgrounds for such devices is vital, but unfortunately has not kept pace. Currently, only very skilled developers are able to develop even simple applications or extant software development frameworks only support a small set of similar devices or a particular application domain.

Toward this end, we present a new programming language, called Em, for the development of highly resourceconstrained device applications. Em is an extension to the C language that integrates high-level language and software engineering features that include modularity, encapsulation and data hiding, interface separation from implementation, inheritance, support for key design patterns, and reduced syntax verbosity, among others.

Em facilitates code reuse, portability across platforms and device components, interchangeability substitutability while still achieving the footprint and code efficiency of C. Em also integrates novel features such as unifying the configuration build time execution and target run time execution code development. We demonstrate the efficacy of Em using multiple embedded systems building blocks and applications.

The quality of a software architecture for component1-based distributed systems is defined not just by its source code but also by other systemic artifacts, such as the assembly, deployment, and configuration of the application compo-nents and their component middleware. They are though, considered as single entity but may refer to each other to work together.

There are measures by which the quality of a design of modules and their interaction among them can be measured. These measures are called coupling and cohesion. Cohesion is a measure that defines the degree of intra-dependability within elements of a module. The greater the cohesion, the better is the program design. Coupling is a measure that defines the level of inter-dependability among modules of a program.

It tells at what level the modules interfere and interact with each other. The lower the coupling, the better the program. The output of software design process is design documentation, pseudo codes, detailed logic diagrams, process diagrams, and detailed description of all functional or non-functional requirements.

The next phase, which is the implementation of software, depends on all outputs mentioned above. Startups need to ensure they select an appropriate one as changing the pattern part way through is a difficult and costly challenge. Once a development team and software development methodology has been chosen, your startup can begin to think about the architecture that will be used during product development.

The act of choosing a software architecture will be the first hurdle that your startup overcomes during the development process. If a startup selects an architecture that makes the design too strict and rigid, it will conflict with agile development methodologies and require too much big design up front.

Alternatively, if the architecture is too loose or not fully implemented, the open boundaries of the design will leave the developers confused. Picking the right software architecture is crucial for the success of the developers. Software design patters are the basis for communication, the plan of the entire software product, and is critical for stakeholder understanding.

There is no single software architecture that can be considered efficient for all software development scenarios. A startup needs to choose an appropriate architecture pattern based upon the given circumstance. All of these components need to be examined to ensure the correct architecture pattern is selected. Once a startup knows some of the features and workflows that they will be creating during development, they can begin to think about different architecture patterns.

These patterns will address issues such as minimizing the business risk, mainlining high availability, and more. As a result, it is important to select the correct one for a given situation. Below details the selection criteria that should be considered when trying to select an appropriate architecture pattern for the proposed software product.

Key Takeaway: Each architecture pattern consists of a basic structure that is used to complete a common software task. Startups need to ensure they select a pattern that will solve their required problem, not just one that might be the easiest to work with.

Reviewing the required product features is the most important aspect of architecture pattern selection. Startups need to ensure that the selected architecture pattern is appropriate for the intended purpose and function of the software product.

Each software architecture pattern has a list of commonly produced applications based on their structure. Key Takeaway: Startups should review their organization when beginning to evaluate different software design patterns. Prior to selecting an architecture pattern, your startup needs to ensure it is a perfect fit for your organization.

Does the proposed pattern fit within the business needs of the startup? Does you selected development team have the expertise required to deliver and maintain the architecture pattern?

A development team that consists of novice developers should stick to more tried and true architecture patterns. This is because there is a rich community that can provide assistance during the creation of the product, as well as multiple historic examples of products created with the pattern that can be referenced.

Startups should focus on the layered or client-server architecture patterns as they are the more simple products to create. This ensures that the selected architecture is appropriate for both the startup as well as the team conducting the work. Startups should choose the simplest appropriate architecture pattern to ensure that the project is completed on time.

Overall, most software architecture problems trying to be solved are variations of previously solved ones. Startups can often find similar architecture patterns, or at least architectural components that can be used to create an overall architecture pattern.

Startups should look at past examples for inspiration and a method to do the work. In conclusion, the selection of an appropriate software architecture pattern is important. This is because the selection must allow your startup to be able to satisfy the business requirements in order to succeed. Commonly, in order for an architecture pattern to success it must have a low fault tolerance, be scalable, as well as being reliable to produce the necessary performance.

Key Takeaway: Selecting an architecture pattern may complicate the software development project. This is because a pattern can increase the amount of work required to create a product. This is especially harmful what a startup could have used an easier solution with less code.

Choosing an architecture pattern will help ease some of the challenges found during software development. Selecting an architecture pattern at the start of the development process, however, may not be the right choice for all startups. Architecture patterns are a great tool when it comes to structural component design.

Using them as a starting point, however, often leads to over-engineered systems of hype-driven-development.

Where startups base their decision based on what is most popular within the development community at that time. Before your startup selects an architecture pattern ensure you think about the overall view of the top level components of your software product. This step is important because architecture patterns should not be considered in being a top level approach as they are primarily valuable when creating the design of one particular component. Overall, startups should thoroughly review all possible software design patterns and their proposed software product before committing to a pattern.

This is because selecting an architecture pattern can complicate the development process at times due to the introduced structure. Key Takeaway: There are a variety of architecture patterns available to use during software development.

Each consists of a set of rules, constraints, and characteristics that are unique to the specific problem that they are trying to solve. Now that your startup knows how to select a software architecture pattern, it is time to learn about the different options available. Every approach comes with its down advantages and disadvantages.

The challenge with selecting an architecture pattern is that one single design approach will not fit every part of your software system. Below are some common patterns, with advantages and disadvantages summarized. You can explore a wide range of other software design patterns here. Each architecture pattern contains a set of rules, constraints and patterns of how to structure a system into a set of elements and connectors. These patterns involve a series of decisions based on a variety of aspects within software development, and each decision can have a significant impact on the overall success of the software.

An architecture or design pattern is therefore tailored to fit a specific structure so that the fundamental idea is reached to solve the common known software architecture problem. The following sections of this article detail the top software architecture patterns available. Key Takeaway: The layered software architecture pattern is one of the most widely known patterns.

It uses layers to separate the code and create a unidirectional relationship between them. This pattern is best suited for general desktop applications, and e-commerce web applications. One of the most well-known software architecture patterns is the layered pattern. This is because this architecture pattern is usually built around a database, and many applications in business naturally lend themselves to storing information within tables.

Many developers use this pattern without really knowing it by name. The core concept of this architecture pattern is splitting the code into different layers. Each layer then has a certain responsibility and provides service to a higher layer. There is no predefined number of layers, but the following are ones that developers see the most often:. The layers have a unidirectional allowed-to-use relationship, where layers can only interact with each other in one direction Figure 1.

Unidirectional relationships plus the creation of isolated layers ensures that refactoring restructuring existing code is easy since any change made within one layer does not affect another.

Variations of this architecture pattern are found depending on the complexity of the developed application. Some project might omit the application layer, while others might add a caching layer.

It is also even possible to merge two layers into one. An example of which is a company named ActiveRecord whose architecture pattern combines the business and persistence layers. Based on the above advantages and disadvantages there are particular situations where using a layered architecture pattern allows your startup to develop software faster, cheaper and with fewer major bugs and issues that need to be solved.

Some examples of suitable situations of when a layered pattern should be used include:. Many of the biggest software frameworks like Java EE, Drupal, and Express were built with this structure in mind so many of the application built with them naturally come out in a layered architecture.

This architecture pattern is commonly used to create a number of different software products, including:. In conclusion, the layered software design pattern allows startups to logically separate the source code into individual layers.
