Content available TRIZ inventive principles and computer design
EN
TRIZ is systematic approach to innovation, being developed since 1950s. This acronym comes from the original Russian name of the methodology, which is usually translated as Theory of Inventive Problem Solving and sometimes abbreviated as TIPS. This methodology offers several concepts and tools supporting identification of problems and generation of solutions, which are directed towards required improvements. This directed approach differentiates TRIZ from other inventive methods, that usually rely on a trial-and-error formula. In the beginning, TRIZ addressed mainly mechanical systems. This paper presents short introduction to TRIZ, describing some basic concepts necessary to show inventive principles in appropriate perspective. These concepts are then used for presenting application examples coming from computer design domain.

W artykule przedstawiono System Modułów Laboratoryjnych SML3, który został opracowany w Instytucie Informatyki Politechniki Warszawskiej (II PW) jako narzędzie do prowadzenia zajęć dydaktycznych oraz wspomagania prac badawczych. System zapewnia łatwy sposób mechanicznego i elektrycznego łączenia modułów. Zbiór modułów zawiera układy SSI, MSI, LSI, a także układy VLSI.

The laboratory system SML3 is a simple tool for modeling and rapid prototyping of complex digital circuits. It can be used in didactic process as well as in research and development works. System contain modules with integrated circuits located on printed boards. The modules can be easily connected mechanically as well as electrically. For electrical connections are used standard 16-pins IDC connectors with 8 pins dedicated for data transfer and 8 pins for power supply. Additionally modules are equipped with special pins for single connections. Designer can select modules from wide module set and selected modules can be located on special frame. Due to simplicity of usage the process of prototyping even complex digital circuits is easy and fast.

Tematem artykułu jest studium użycia układu FPGA do emulacji działania mikroprocesora w zastosowaniach dydaktycznych. Zaprezentowano proces powstawania rozwiązania od etapu analizy wymagań, przez architekturę do opisu implementacji, ze wskazaniem istotnych uwarunkowań użytkowych i technologicznych oraz kluczowych decyzji. Wynikiem przedstawionych prac jest moduł użyty po raz pierwszy w zajęciach laboratoryjnych w bieżącym semestrze.

The paper presents a case study of using the FPGA chip for emulating a microprocessor system for didactic purposes. Inside the FPGA chip there are implemented an open source Z80 processor core together with code and data memory blocks connected to the proces-sor bus as well as UART peripheral. The emulated processor bus behaviour is compliant with the original Z80 bus. Therefore, a student is able to connect external devices to the bus (by means of the appropriate connectors, three-state buffers and address decoding circuits). The UART peripheral, which is connected to the external USB/UART converter, is used by the NoICE commercial monitoring application. By means of this application, a student is able, among others, to load own program to the Z80 system, execute the code stepwise or in the free run mode, observe and modify content of the memory connected to the Z80 processor bus. Z80 processor core is shared between the NoICE monitor program and the user's code. The presented hardware platform allows for implementation of other 8-bit microprocessors as well. This way students may learn the modern System On Chip concept (SOC). Moreover, the module can be also used to teach the issues of logic circuit implementation inside the FPGA. The result of presented work is a versatile laboratory module, used since 2010 in the microprocessor systems laboratory at the Warsaw University of Technology.

Dobrano najlepszy nośnik strukturalny i przedstawiono sposób osadzania katalizatora wanadowo- fosforowego na nim. Złoże katalityczne umieszczono w reaktorze rurowym i zrealizowano proces selektywnego utleniania n-butanu do bezwodnika maleinowego. Uzyskano dobre stopnie konwersji i selektywność do bezwodnika maleinowego. Przebadany nośnik można zastosować w reaktorach przemysłowych do otrzymywania tego bezwodnika.

The best structured carrier has been selected and a manner has been presented of depositing on it a vanadia- phosphoria catalyst. The catalyst packing has been placed into a tubular reactor and a process of selective oxidation of n-butane to maleic anhydride has been realised. The conversion and selectivity towards maleic anhydride were quite good. The carrier studied could be applied in the industrial plants of maleic anhydride.
