Available in PDF, EPUB and Kindle. Book excerpt: The number of applications using the Ada language is increasing rapidly with the availability of over 200 base and derived validated compilers. Reports indicate that many of these applications have been successfully developed from reusable software parts or have been developed to yield reusable software parts. In contrast of these reports, other applications have identified deficiencies in the Ada RunTime Environment (RTE) that have necessitated restricted use of the Ada with a consequent impact on the potential reuse of Ada software. Therefore, improving the reuse of software in these applications depends to some extent upon careful analysis and understanding of the issues related to software reuse and the Ada RTE. The latter applications typically comprise embedded Mission Critical Computer Resource (MCCR) systems that must satisfy real-time performance constraints that are usually dependent upon specialized hardware. These constraints have caused the intrusion of non-Ada code into the applications and the exploitation of specific idiosyncrasies of the RTE that are within the semantic fringes of the Ada standard DoD83. While reducing the use of non-Ada code may not be feasible for applications that must interact with special controls, devices, and weapon systems, ameliorating the deleterious effects of deficiencies and idiomatic behavior of the RTE on the reuse of Ada parts must receive prompt attention.

Available in PDF, EPUB and Kindle. Book excerpt: The study is intended to define the characteristics of an Ada Runtime Environment that effectively supports the development of real-time applications. The study was undertaken with the specific objective of supporting the selection of a runtime environment for the JINTACCS Automated Message Preparation System (JAMPS) program, but provides results useful in any real-time system acquisition program. A major goal of the JAMPS Ada software acquisition is to develop highly portable and reusable implementation that can be used in many different military systems. This goal impacts the selection and use of the runtime environment, as dependence on particular features of the runtime environment (either for functionality or performance) limits portability to only those systems providing the same features. This results in the concept of a minimal set of runtime environment features necessary to support JAMPS. Implementing JAMPS with dependence only on these features will allow portability within the class of systems providing those features. This report identifies such a minimal set of environment features. Keywords: fault tolerant computing; input output processing; data storage systems.

Download or read book Guideline to Select Configure and Use an Ada Runtime Environment written by LABTEK CORP WOODBRIDGE CT. and published by . This book was released on 1989 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ada Language has incorporated many features such as tasking, dynamic storage management, and exception handling that require substantial execution-time support. Most of these features were not previously available in commonly used real-time languages, but were instead provided by an separate executive. The inclusion of these features into the language expands the possibility for transportable and reusable software, but complicates the software development process to some degree. Engineers that previously had familiarity with their own executives, now are forced to accept the code of a compiler vendor for the execution-time support. This guide has been written to help software developers in the difficult task of selecting, configuring, and using a runtime that will meet the needs of their application. The wide variety of applications for which Ada is used necessitates considerable flexibility within the implementation of the runtime code. Different algorithms for tasking, storage management, interrupt handling, and exception propagation can radically effect the behavior of real-time programs. Variations among compilers for the same processor can be as great as a factor of six in runtime size and factor of eleven in tasking performance. It is therefore essential that software developers completely understand the characteristics of the available runtimes prior to selecting one for use on a project. (kr).

Download or read book An Approach to Tailoring the Ada Runtime Environment written by IIT RESEARCH INST LANHAM MD. and published by . This book was released on 1989 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is an investigation of Run Time Environment tailoring. It attempts to answer the following questions: (1) What is tailoring?; (2) How can one determine whether an RTE can be tailored?; (3) What can one do to tailor an RTE?; (4) What are the possible side effects of tailoring?; (5) What are the costs of tailoring?; and (6) What can vendors do to make RTEs more tailorable? To a limited extent, the performance of Ada programs can be improved by techniques other than changing the code of the RTE. This research, however, specifically addresses tailoring the code of the RTE to improve the performance or functionality of Ada executables. This effort is also targeted at real-time systems that are to be embedded in bare computers where both the application and executive services are implemented through Ada constructs and the RTE. This research is not intended to establish direction for changes to a future Ada standard. It is intended to suggest near-term software engineering practices that conform to the Ada standard and can be applied when it is necessary to tailor the Ada RTE for highly constrained applications. It is also hoped that vendors will use this research to provide design features in Ada compilers that make it straightforward to employ these practices. (kr).

This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the proceedings of the Sixth Symposium on Empirical Foundations of Information and Software Sciences (EFISS), which was held in Atlanta, Georgia, on October 19-21, 1988. The purpose of the symposia is to explore subjects and methods of scientific inquiry which are of common interest to information and software sciences, and to identify directions of research that would benefit from the mutual interaction of these two disciplines. The main theme of the sixth symposium was modeling in information and software engineering, with emphasis on methods and tools of modeling. The symposium covered topics such as models of individual and organizational users of information systems, methods of selecting appropriate types of models for a given type of users and a given type of tasks, deriving models from records of system usage, modeling system evolution, constructing user and task models for adaptive systems, and models of system architectures. This symposium was sponsored by the School of Information and Computer Science of the Georgia Institute of Technology and by the U.S. Army Institute for Research in Management Information, Communications, and Computer Sciences (AIRMICS). 17le Editors vii CONTENTS 1 I.
