An extensible,maintainable and elegant approach to hardware source code generation in Reconfig-P

Reconfig-P is a prototype hardware implementation for membrane computing applications. Currently there are two alternative designs for the implementation of P systems in Reconfig-P: the rule-oriented design and the region-oriented design. Driven by the goal of high performance, the rule-oriented design treats reaction rules as the primary computational entities and represents regions only implicitly. In contrast, the region-oriented design represents regions, rather than reaction rules, as the primary computational entities, and thereby more directly reflects the intuitive conceptual understanding of a P system and promotes the extensibility of Reconfig-P. To improve its practical usefulness and versatility, not only should Reconfig-P include both of the hardware designs, it should be maintainable and extensible so that it can easily and effectively incorporate new implementation strategies and implementations of additional types of P systems. To accomplish a seamless integration of the rule-oriented and region-oriented designs and other alternative implementation strategies in Reconfig-P, and to make Reconfig-P amenable to future integration of additional implementation strategies, we have developed a new version of P Builder, our intelligent hardware source code generator, in accordance with a novel design pattern called Content-Form-Strategy. In this paper, we describe the Content-Form-Strategy pattern and the implementation of the new version of P Builder.     

Impact of information technology on users' work environment: A case of computer aided design (CAD) system implementation

Study of the possible impacts of a new information system or technology on its users is an important area of MIS research. Understanding and identifying favorable and unfavorable impacts of implementation on users should be helpful in developing better design guidelines and choices to take full advantage of the potential of information technology, while minimizing the possible negative consequences for users. This paper presents the details of impacts created by the implementation of a computer aided design (CAD) system for part designers at an automotive parts manufacturer. The paper employs equity–implementation (E–I) model as a framework to help identify and analyze the impacts of CAD technology implementation on part designers' work environment. The paper identifies changes in the designers' inputs and outcomes as a result of CAD implementation. On the whole the impacts were found to be favorable for designers, the manufacturing organization, and its customers. The paper concludes that the E–I model provides a useful framework to help assess the nature of impacts created by the new system. The reactions of designers to the new system were also found to be consistent with the E–I model.

Software reverse engineering: A case study

This paper presents lessons learned from an experiment to reverse engineer a program. A reverse engineering process was used as part of a project to develop an Ada implementation of a Fortran program and upgrade the existing documentation. To accomplish this, design information was extracted from the Fortran source code and entered into a software development environment. The extracted design information was used to implement a new version of the program written in Ada. This experiment revealed issues about recovering design information, such as, separating design details from implementation details, dealing with incomplete or erroneous information, traceability of information between implementation and recovered design, and re-engineering. The reverse engineering process used to recover the design, and the experience gained during the study are reported.
