Desarrollo integral de sistemas de procesamiento de informacion visual: Un enfoque multiparadigma basado en lineas de producto, componentes y generacion automatica de software.

摘要

The wide variety of today software systems has significantly increased the size and complexity of applications. This, together with the rapid technological advances in some fields such as electronics or communications, makes it necessary to develop software flexible enough to handle the continuous market changes in a time-effective manner. It is equally essential not to achieve this application flexibility improvement by reducing their efficiency or increasing their cost or time to market.; During the last few decades new software development paradigms have arisen in response to these new demands. Among them, Object and Aspect Oriented, Component and Product Line Based Software Development paradigms, together with Generative and Visual Programming are some outstanding examples. However, these proposals have not found a significant acceptance among the community of mixed hardware/software (HW/SW) system developers. This can be partially attributed to the lack of agreement with respect to the methodologies and notations to be adopted as well as to the absence of tools which fully support the whole development life cycle of these applications. In fact, this type of systems are currently developed in a rather hardware-centric fashion while software is attributed a less important role. This approach usually leads to developing highly efficient systems which, on the other hand, are scarcely (if at all) flexible and reusable.; This Thesis presents a novel software-centric approach to mixed HW/SW system development which is aimed at improving this kind of product flexibility and reusability while bearing in mind other requirements regarding efficiency, reliability, low cost, or short time to market. This new approach is built on the foundation of Software Product Lines while leveraging the capabilities offered by Component-Based Software Development and Generative Programming. In order to show the synergy arising from the integration of these three current Software Engineering hot topics, this Thesis present a practical study case on building Visual Information Processing Systems (VIPS), which can be easily extended to cover many other application domains, e.g. real-time control systems or networking applications. In order to support the multi-paradigm approach presented here, the IP-CoDER visual programming tool has been developed which covers the whole YIPS development life-cycle allowing the integration of several image processing libraries and tools currently available.
