Volume 28, Number 1, March 2007 Ada User Journal 3 Editorial In the foreword to volume 28 of the Ada User Journal, which commences with the present issue, our memory goes to one very good and one very sad news that opened the year 2007 by occurring in the short span of two calendar days: On January 24, the Amendment to ISO/IEC 8652 (which we call and will keep calling ‘Ada 2005’ in the vernacular) was finally approved by ISO. All nations who participate in WG9 voted to approve and no comments were submitted, which were definite tokens of excellent technical work and also cohesive and determined national support. And that was a very good news indeed. (For the record, it took in fact another 7 weeks, until March 9, for the Amendment to be finally published on the ISO calatogue. But then it was.) The sad news came only two days after that. On January 26, Jean Ichbiah, the man who designed Ada, passed away at 66. I have read many nice words about Jean Ichbiah from various authorities who wrote about him, and more you will read for yourselves in the News section of this issue. I have to say however that I was most impressed by some passages of the obituary that the Boston Globe run about him shortly after his death. I wish to share some excerpts of that with you in this editorial. Jean said in 1984 in an interview to the CACM celebrating the birth of Ada: "I see myself really as an architect, […] My work was not to invent new things; it was not research work, it was architectural work. I had to integrate the best available materials to construct the building that would best suit the requirements of the users." He viewed the Ada language "as a cathedral with all the architectural lines interwoven in a harmonious manner," I find this is a very good way of remembering who Jean Ichbiah was to the Ada community. It is so very sad that he passed away. It is reassuring and conforting though that his creature is still well and alive some 30 years after he took it on himself to design it. Returning to the more mundane task of illustrating the contents of the issue and the plans for the remainder of the volume, I am pleased to welcome the contribution of Romain Berrendonner and Cyrille Comar of the Paris offices of AdaCore, who report on the development and experimental use of a software infrastructure commissioned by the European Space Agency for benchmarking the space and time performance of Ravenscar technology and applications. The report on that project constitutes the technical matter of the present issue. Future issues will have reports from the IRTAW-13 workshop, which will take place in April at Woodstock, Vermont, USA (cf. the technical program in this issue) and staggered proceedings of the industrial track of the Ada-Europe 2007 conference, which will be held in Geneva, CH, in June. The rest of the issue contains news, and calendar events of interest to the Ada community, as usual, gathered for you from our News and Calendar editors.

  • Introduction to Embedded C
    INTRODUCTION TO EMBEDDED C by Peter J. Vidler Introduction The aim of this course is to teach software development skills, using the C programming language. C is an old language, but one that is still widely used, especially in embedded systems, where it is valued as a high- level language that provides simple access to hardware. Learning C also helps us to learn general software development, as many of the newer languages have borrowed from its concepts and syntax in their design. Course Structure and Materials This document is intended to form the basis of a self-study course that provides a simple introduction to C as it is used in embedded systems. It introduces some of the key features of the C language, before moving on to some more advanced features such as pointers and memory allocation. Throughout this document we will also look at exercises of varying length and difficulty, which you should attempt before continuing. To help with this we will be using the free RapidiTTy® Lite IDE and targeting the TTE®32 microprocessor core, primarily using a cycle-accurate simulator. If you have access to an FPGA development board, such as the Altera® DE2-70, then you will be able to try your code out in hardware. In addition to this document, you may wish to use a textbook, such as “C in a Nutshell”. Note that these books — while useful and well written — will rarely cover C as it is used in embedded systems, and so will differ from this course in some areas. Copyright © 2010, TTE Systems Limited 1 Getting Started with RapidiTTy Lite RapidiTTy Lite is a professional IDE capable of assisting in the development of high- reliability embedded systems.

This has, in turn, motivated new Operating System (OS) designs to manage these het- erogeneous processors and accelerators systematically. M3 [9] is an OS following the microkernel approach. M3 uses a hardware/- software co-design to exploit the heterogeneous systems in a seamless and effi- cient form. It achieves that by abstracting the heterogeneity of the cores via a Data Transfer Unit (DTU). The DTU abstracts the heterogeneity of the cores and accelerators so that they can communicate systematically. I have been working to enhance the programming environment in M3 by porting a C library to M3. I have evaluated different C library implementations like the GNU C Library (glibc), Musl, and uClibc. I decided to port Musl as it has a relatively small code base with fewer configurations. It is simpler to port, and it started to gain more ground in embedded systems which are also a perfect match for M3 applications.

  • A Model-Driven Development and Verification Approach
    A MODEL-DRIVEN DEVELOPMENT AND VERIFICATION APPROACH FOR MEDICAL DEVICES by Jakub Jedryszek B.S., Wroclaw University of Technology, Poland, 2012 B.A., Wroclaw University of Economics, Poland, 2012 A THESIS submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Computing and Information Sciences College of Engineering KANSAS STATE UNIVERSITY Manhattan, Kansas 2014 Approved by: Major Professor John Hatcliff Abstract Medical devices are safety-critical systems whose failure may put human life in danger. They are becoming more advanced and thus more complex. This leads to bigger and more complicated code-bases that are hard to maintain and verify. Model-driven development provides high-level and abstract description of the system in the form of models that omit details, which are not relevant during the design phase. This allows for certain types of verification and hazard analysis to be performed on the models. These models can then be translated into code. However, errors that do not exist in the models may be introduced during the implementation phase. Automated translation from verified models to code may prevent to some extent. This thesis proposes approach for model-driven development and verification of medi- cal devices. Models are created in AADL (Architecture Analysis & Design Language), a language for software and hardware architecture modeling. AADL models are translated to SPARK Ada, contract-based programming language, which is suitable for software veri- fication. Generated code base is further extended by developers to implement internals of specific devices. Created programs can be verified using SPARK tools. A PCA (Patient Controlled Analgesia) pump medical device is used to illustrate the primary artifacts and process steps.

  • 2D-Spieleprogrammierung in Freebasic
    Dieser Abschnitt behandelt QuickBASIC und dessen abgespeckte Version QBASIC gleichermaßen; der Einfachheit halber wird nur von QuickBASIC gesprochen. Wer noch nie mit QuickBASIC in Berührung gekommen ist, kann den Abschnitt getrost überspringen – er ist eher für Programmierer interessant, die von QuickBASIC zu FreeBASIC wechseln wollen. Trotz hoher Kompatibilität zu QuickBASIC gibt es eine Reihe von Unterschieden zwischen beiden BASIC-Dialekten. Einige davon beruhen auf der einfachen Tatsache, dass QuickBASIC für MS-DOS entwickelt wurde und einige Elemente wie beispielsweise direkte Hardware-Zugriffe unter echten Multitaskingsystemen wie höhere Windows- Systeme oder Linux nicht oder nur eingeschränkt laufen. Des Weiteren legt FreeBASIC größeren Wert auf eine ordnungsgemäße Variablendeklaration, womit Programmierfehler leichter vermieden werden können. Hinweis: Mit der Compiler-Option -lang qb kann eine größere Kompatibilität zu QuickBASIC erzeugt werden. Verwenden Sie diese Option, um alte Programme zum Laufen zu bringen. Mehr dazu erfahren Sie im Kapitel ??, S. ??. • Nicht explizit deklarierte Variablen (DEF###) In FreeBASIC müssen alle Variablen und Arrays explizit (z. B. durch DIM) deklariert werden. Die Verwendung von DEFINT usw. ist nicht mehr zulässig. • OPTION BASE Die Einstellung der unteren Array-Grenze mittels OPTION BASE ist nicht mehr zulässig. Sofern die untere Grenze eines Arrays nicht explizit angegeben wird, verwendet FreeBASIC den Wert 0. • Datentyp INTEGER QuickBASIC verwendet 16 Bit für die Speicherung eines Integers. In FreeBASIC sind es, je nach Compilerversion, 32 bzw. 64 Bit. Verwenden Sie den Datentyp SHORT, wenn Sie eine 16-bit-Variable verwenden wollen. • Funktionsaufruf Alle Funktionen und Prozeduren, die aufgerufen werden, bevor sie definiert wurden, müssen mit DECLARE deklariert werden. Der Befehl CALL wird in FreeBASIC nicht mehr unterstützt.
