Software architecture: practice, potential, and pitfalls

Abstract: Whatever the long-term impact of software architecture may turn out to be, an appropriate starting point is a concrete appraisal of the current state of the practice in the use of software architecture. It is the purpose of the article to take a step in this direction. It provides concrete examples of what is now possible when architectural principles are applied to industrial problems in systematic ways, considers the potential impact of software architecture over the next few years, and suggests steps that should be taken to bring this about. >

Extending the ATAM Architecture Evaluation to Product Line Architectures

Abstract: Architecture-based development of software product lines requires well established methodologies for both development and assessment of software product line architectures. While several methodologies for the development of such systems have been proposed, their assessment has mostly relied on methods developed for single product architectures. In this paper, we extend the popular ATAM (Architecture Tradeoff Analysis Method) method to cover both the core architecture of the product line and the individual product architectures. In addition, the extended method prescribes a qualitative analytical treatment of variation points using scenarios. We present the main tenets of the new method and illustrate its use through a small case study.

A3 Architecture overviews. A tool for effective communication in product evolution

Abstract: Creating products from scratch is time consuming and costly. Evolving an existing product is a strategt often chosen by companies to meet customer demands in a timely manner. Evolving a product however poses great challenges, especially if the product is a complex system. The ability of a system to be easily evolved is termed evolvability. Evolvability refers to how a system design changes frome one generation to the next, such as specifying which aspects of the design are passed down and which are new to the previous generation. Over the years, technologies, designs and implementations of systems may have changed completely. It may be only the architecture that remains from the original system. Architectures, once consolidated in an architecture description, provide a framework in which evolution can be performed, enable early analysis, facilitate communication among stakeholders, etc. The process of creating architectures is called architecting. This responsibility lies with the architect. A major need of architects is to share architecture knowledge. This is however not common practice in most companies. In addition, even if a knowledge sharing mechanism successes in delivering architecture knowledge, if this knowledge cannot be effectively communicated to the variety of stakeholders, it can render a great architecting work ineffective. The A3 Architecture Overview is a tool meant for effective communication of architecture knowledge. An A3 Architecture Overview uses two sides of an A3 sheet. One side displays a structured model (A3 Model), composed of several interconnected views, while the other side displays structured textual information (A3 Summary). The A3 Architecture Overview has been used in real industrial projects at Philips Healthcare as a communication tool to share architecture knowledge. Experiences and feedback in its use and creation have shown that it is a powerful tool for effective communication in product evolution and an improvement in the way companies share architecture knowledge.

Principles of Computer Architecture

Abstract: From the Publisher: FEATURES/BENEFITS Choice of the instruction set architecture (ISA). The mainstream ISA "ARC" is a subset of the commercial SPARC, which strikes a balance between the complexity of a real-world architecture and the need for a simple instructional ISA.
