TLMCO-simulation for an open source MPSOC platform under STARSoC environment
2008
In the last decade, the embedded systems become more and more complex. This complexity is due to the fact that these systems contain more heterogeneous hardware and software components (CPUpsilas, DSP, IP, etc.). Such systems called multiprocessor-on-chip (MPSoC) require new design approaches in order to satisfy several constraints, verification time, cost and time to market.
PRISMA: towards quality, aspect oriented and dynamic software architectures
2003
The development of software systems must be done using platforms that allow the description of quality, complex, distributed, dynamic and reusable architectural models. We present in this paper PRISMA, an architectural modelling approach based on aspects and components that uses a component definition language (components, connectors and systems) to define architectural types at a high abstraction level and a configuration language to design the architecture of software systems. The component definition language increases reuse allowing importation of COTS and reduces complexity by integrating two modern software development approaches: component-based software development and aspect-orient…
From Strategy to Code: Achieving Strategical Alignment in Software Development Projects Through Conceptual Modelling
2021
In this article we propose S2C, a strategy-to-code methodological approach to integrate organisational, business process, and information system modelling levels to support strategic alignment in software development. Through a model-driven approach and under the Conceptual-Model Programming paradigm, the proposal supports the semi-automatic generation of working software, as well as traceability among the modelling levels. Via a working example, we illustrate how strategic definitions can be traced into specific software components by the integration of three modelling methods: Lite*, for modelling strategic reaction to external influences, Communication Analysis, for business process mode…
Rapid prototyping platform for stream-oriented reconfigurable computing applications
2010
In this paper we present a methodology and tool for rapid prototyping of real time image processing applications. We describe our design flow of multiprocessor system on chip (MPSoC) architectures based on hardware/software components. This methodology provides automated methods to specify, generate the hardware, software, and the architectural interfaces between them. Our methodology starts from system level specification of the application with parallel processes described in C-code. The processes communicate through an abstract channel called streams. We describe also the solution that we proposed to synthesize a custom bus architecture for the reconfigurable computing applications, whic…
Use and Identification of Components in Component-Based Software Development Methods
2000
New software systems are needed ever more but to keep up with this trend software developers must learn to create quality software more efficiently. One approach is to (re-)use components as building blocks of the new software. Recently there has been more interest to create component-based software development methods to support this. In this article we first set out requirements for reuse-based software development and then evaluate three component-based methods, namely Catalysis, OMT++, and Unified Process. As a conclusion we argue that evaluated methods produce prefabricated components and that component-based means that software developers can change better components to existing syste…
Developing Software with Domain-Driven Model Reuse
2015
This chapter presents an approach to software development where model-driven development and software reuse facilities are combined in a natural way. It shows how model transformations building a Platform Independent Model (PIM) can be applied directly to the requirements specified in RSL by domain experts. Further development of the software case (PSM, code) is also supported by transformations, which in addition ensure a rich traceability within the software case. Alternatively, the PSM model and code can also be generated directly from requirements in RSL, thus providing fast development of the final code of at least a system prototype in many situations. The reuse support relies on a si…
A speech recognition approach for an industrial training station
2021
This paper presents a speech recognition service used in the context of commanding and guiding the activities around an industrial training station. The entire concept is built on a decentralized microservice architecture and one of the many hardware and software components is the speech recognition engine. This engine grants users the possibility to interact seamlessly with other components in order to ensure a gradual and productive learning process. By working with different API’s for both English and Romanian languages, the presented approach manages to obtain good speech recognition for defining task phrases aiding the training procedure and to reduce the recognition required time by a…
XPL, a Presentation Language based on User Interface Design Pattern
2007
The great diversity of presentations in software applications deals with fulfillment of various type of graphic interface constructions related to different programming Languages. Moreover, in the Internet era html pages play a main role because of the increasing complexity of Web applications. In Software Engineering, the use of design patterns is proven remarkable for the design and reuse of software components. Visual Design. Patterns (ViDP) are useful to define interaction schemas between. user and computer. By the some token, visual design. patterns are useful to incorporate common interfaces of interaction, schemas between user and computer. This paper describes the eXtensible Present…
XPL and the Synchronization of Multimodal User Interfaces based on Design Pattern
2008
The great diversity of presentations in software applications deals with fulfilment of various types of user interface constructions related to different programming languages. Furthermore, the growing interest for multimodal applications entails that their user interfaces have to support multiple access channels within a single development framework. User Interfaces Design Patterns (UIDPs) are helpful to define interaction schemas between user and computer and they provide remarkable tools for the design and reuse of software components. This paper describes the eXtensible Presentation architecture and Language (XPL), a framework aimed at streamlining multi-channel interface design process…
Editorial: Software language engineering
2008
Software languages play an important role in software development. Software languages are the artificial languages that are used to describe software systems at various abstraction levels. They are applied to describe requirements and designs for software, definitions of software architectures, and implementations of software systems. A huge variety of different technological spaces exist to describe languages: programming languages, software modeling languages, data modeling languages, domain-specific languages, ontology language, and others.
