本研究の目的は,工業高校の「プログラミング技術」の授業における,入出力設計に関する知識の定着や技術の習得をねらいとした実習用教材の開発及び製作題材の試作を行うことである。教材開発に先立ち,工業高校のプログラミング用教材のハードウェアとして,[1]電子機器の接続が容易で,組み立てにおけるハードウェア面での負担が少ないこと,[2]プログラムの書き込みと動作確認の手順が簡略化できることから,ワンボードマイコンであるArduinoを取り扱うこととした。Arduinoを用いた学習内容として,「LED制御によるディジタル信号の入出力制御を学習する電子サイコロの製作題材」,「PWM制御によるアナログ信号の入出力制御を学習するモータ制御によるロボットカーの製作題材」を開発した。これらの製作題材を用いた学習を行うことで,既存の制御用教材であるPICを用いた学習よりも,学習者に対するコーディング以外の負担が少なくなることや,プログラミング技術で学ぶ制御を統合的に取り入れることが可能になることが期待できる。, The objective of this paper is to perform a prototype of development and production subject of training teaching material in the class of the “programming technology" of technical high school. It makes the fixing of the knowledge of the input and output design and acquisition of technology an aim. Previously to the development, it was decided to deal with the Arduino of a one-board microcomputer as hardware for the teaching material. Its strong point is [1]Easy connection of the electronic device, it is less of a burden on the hardware aspects of the assembly [2]The operation confirmation of the procedure and writing of program can be simplified. As a learning content using the Arduino, we developed 「Electronic dice fabricated material learning input and output control of the digital signal by the LED control」 and 「Production Subjects of autonomous car by the motor control to learn the input and output control of the analog signal by PWM control」. By learning of using these production material, the following 2points can be expected to become possible than learning with what is existing control for material. (1) That the burden of non-coding for the learner becomes less. (2) To incorporate control to learn a programming technology in an integrated manner.

Parallel architectures with physically distributed memory providing computing cycles and large amounts of memory are becoming more and more common. To make such architectures truly usable, programming models and support tools are needed to ease the programming effort for these parallel systems. Automatic data distribution tools and techniques play an important role in achieving that goal. This paper discusses state-of-the-art approaches to fully automatic data and computation partitioning. A kernel application is used as a case study to illustrate the main differences of four representative approaches. The paper concludes with a discussion of promising future research directions for automatic data layout.

В роботі розглянуто питання щодо забезпечення прогнозованої якості програмного продукту під час побудови програмних комплексів. Не є секретом те, що процес програмування тісно пов’язаний із процесами композиції та декомпозиції. Однак на сьогоднішній день частину цього процесу віддають на відкуп програмістові, ґрунтуючись на його досвіді та попередніх здобутках.

The problem of preparation of a program to perform it on multiprocessor system of a cluster type is considered. When developing programs for a cluster computer the technology based on use of the remote terminal is applied. The situation when such remote terminal is the computer with operational system Windows is considered. The set of the tool means, allowing carrying out of editing program texts, compiling and starting programs on a cluster computer, is suggested. Advantage of an offered way of preparation of programs to execution is that it allows as much as possible to use practical experience of programmers used to working in OS Windows environment.

Der Wunsch, digitale Schaltungen mit komplexen PLDs zu realisieren, geht zwangsläufig einher mit der Entscheidung für eine bestimmte Bausteinfamilie. Hier die richtige Wahl zu treffen ist insbesondere für Neueinsteiger nicht immer einfach. Der vorgestellte Ansatz geht nicht von abstrakten Teststrukturen aus. Statt dessen zeigt er die möglichen Anforderungen konkreter Schaltungen auf, um auf dieser Basis eine Bausteinauswahl zu erleichtern.
