Different classes of problems on the embedded systems market and its needs make manufacturers of embedded systems to design heterogeneous many/multi core hardware platforms. Such platforms includes dozens of different cores: CPU, GPU, DSP, FPGA etc. That makes them incredibly hard to program, especially in case when domain experts are involved in the development process. Usually, domain expert has knowledge in his domain area, but does not fully understand the specificity of programming for heterogeneous manycore platforms. In this article, we propose the complex technology and tools that allows involving domain experts in software development for embedded systems. The proposed technology has various aspects and abilities that can be used to build verifiable and portable software for a wide range of heterogeneous embedded platforms.

Nowadays embedded systems are used in a broad range of domains such as avionics, space, automotive, mobile, domestic appliances etc. Sophisticated software determines the quality of embedded systems and requires high-qualified experts for software development. Software becomes the main assert of embedded systems that is valuable to retain in changing computing platforms in embedded systems evolution. Computing platforms for embedded systems became multicore processors and SoC, they can change in the embedded system lifetime that could be long (dozen of years for an automobile and airplane). It requires software porting to new platforms as a regular process. Many tools and approaches allow developing of software for domain area experts, but mainly for general-purpose computing systems. In this paper the authors present the complex technology and tools that allows involving domain experts in software development for embedded systems. The proposed technology has various aspects and abilities that can be used to build verifiable and portable software for a wide range of embedded platforms.

In this paper, we propose a new approach for managing domain specific thesauri, where object-oriented paradigm is applied to thesaurus construction and query-based browsing. The approach provides an object-oriented mechanism to assist domain experts in constructing thesauri; it determines a considerable part of relationship degrees between terms by inheritance and supplies the domain expert with information available from other parts of the thesaurus being constructed or already constructed. In addition to that, it enables domain experts to incrementally construct the thesaurus, since the automatically determined relationship degrees can be refined whenever a more sophisticated thesaurus is needed. It may minimize domain experts' burden caused by the exhaustive specification of individual relationship. This approach also provides a query-based browsing facility, which enables users to find desired thesaurus terms without tedious browsing in the thesaurus. A browsing query can be formulated with terms rather ambiguous, yet capable of deriving the desired terms. This browsing query is useful especially when users want precise results. In other words, it is useful when they want to use only thesaurus terms carefully selected in reformulating Boolean queries. To demonstrate the feasibility of our approach, we fully implemented an object-based thesaurus system, which supports the semiautomatic thesaurus construction and the query-based browsing facility.

The 21st century is the era of Ubiquitous Computing where computing devices are present everywhere in our lives. To satisfy the development of this tendency, many hardware platforms have been proposed for developing Ubiquitous devices. Among them, T-Engine, an open standardized development platform for embedded systems, is one of the most popular platforrms. It is nowadays compatible with embedded equipments for a wide range of fields. In Vietnam, T-Engine has just been introduced for 4 years. However, most of the ubiquitous applications using T-Engine are developed restrictively based on the standard hardware of T-Engine. One issue that arises is the necessity of a solution to expand T-Engine hardware and use it to control automatic systems to satisfy different types of Ubiquitous devices. This research is to propose an approach to use T-Engine in the Ubiquitous Devices that require the attachment of the additional hardware as well as the complicated control mechanism with real time constraints. In this research, we proposed an expanding solution T-Engine through the extension bus. Besides that, we consider the timing problems in bus transaction and problems in real-time programming. A simple robot demonstration has also been designed and implemented to prove the feasibility of our model. This approach will open up a new tendency of developing complicated Ubiquitous devices using T-Engine in Vietnam.

In general, designing a domain-specific language (DSL) is a complicated process, requiring the cooperation of experts from both application domain and computer language development areas. One of the problems that may occur is a communication gap between a domain expert and a language engineer. Since domain experts are usually non-technical people, it might be difficult for them to express requirements on a DSL notation in a technical manner. Another compelling problem is that even though the majority of DSLs share the same notation style for representing the common language constructs, a language engineer has to formulate the specification for these constructs repeatedly for each new DSL being designed. The authors propose an innovative concept of computer language patterns to capture the well-known recurring notation style often seen in many computer languages. To address the communication problem, they aim for the way of proposing a DSL notation by providing program examples as they would have been written in a desired DSL. As a combination of these two ideas, the chapter presents a method for example-driven DSL notation specification (EDNS), which utilizes computer language patterns for semi-automated inference of a DSL notation specification from the provided program examples.

Domain-Specific Languages (DSLs) can be regarded as User Interfaces (UIs) because they bridge the gap between the domain experts and the computation platforms. Usability of DSLs by domain experts is a key factor for their successful adoption. The few reports supporting improvement claims are persuasive, but mostly anecdotal. Systematic literature reviews show that evidences on the effects of the introduction of DSLs are actually very scarce. In particular, the evaluation of usability is often skipped, relaxed, or at least omitted from papers reporting the development of DSLs. The few exceptions mostly take place at the end of the development process, when fixing problems is already too expensive. A systematic approach, based on techniques for the experimental evaluation of UIs, should be used to assess suitability of new DSLs. This chapter presents a general experimental evaluation model, tailored for DSLs’ experimental evaluation, and instantiates it in several DSL’s evaluation examples.

Due to the increase in popularity of mobile devices, it has become necessary to develop a low-power design methodology in order to build complex embedded systems with the ability to minimize power usage. In order to fulfill power constraints and security constraints if personal data is involved, test and verification of a design's functionality are imperative tasks during a product's development process. Currently, in the field of secure and reliable low-power embedded systems, issues such as peak power consumption, supply voltage variations, and fault attacks are the most troublesome. This chapter presents a comprehensive study over design analysis methodologies that have been presented in recent years in literature. During a long-lasting and successful cooperation between industry and academia, several of these techniques have been evaluated, and the identified sensitivities of embedded systems are presented. This includes a wide range of problem groups, from power and supply-related issues to operational faults caused by attacks as well as reliability topics.

AbstractModel-driven engineering (MDE) addresses central aspects of robotics software development. MDE could enable domain experts to leverage the expressiveness of models, while implementation details on different hardware platforms would be handled by automatic code generation. Today, despite strong MDE efforts in the robotics research community, most evidence points to manual code development being the norm. A possible reason for MDE not being accepted by robot software developers could be the wide range of applications and target platforms, which make all-encompassing MDE IDEs hard to develop and maintain. Therefore, we chose to leverage a large corpus of open-source software widely adopted by the robotics community to extract common structures and gain insight on how and where MDE can support the developers to work more efficiently. We pursue modeling as a complement, rather than imposing MDE as separate solution. Our previous work introduced metamodels to describe components, their interactions, and their resulting composition. In this paper, we present two methods based on metamodels for automated generation of models from manually written artifacts: (1) through static code analysis and (2) by monitoring the execution of a running system. For both methods, we present tools that leverage the potentials of our contributions, with a special focus on their application at runtime to observe and diagnose a real system during its execution. A comprehensive example is provided as a walk-through for robotics software practitioners.
