An 8-bit Microcontroller S/W Development Environment and Its ExtensionLiu, Yung-chih 30 July 2007 (has links)
In this thesis, the first section will talk about how to implement the software development environment for 8bit microprocessor, including Compiler, Assembler, and Debugging mechanism etc. The design of Debugging mechanism is based on in-circuit emulator.
In-circuit emulator is a common debugging technique for microprocessor. The designed ICE contains hardware implement and debugging software for it in this thesis. ICE hardware is a control circuit from TAP Controller, IEEE 1149.1 std. and it control the scan cells on the data bus. The Debugging software uses JTAG port, IEEE 1149.1 std., to insert debug instruction from PC to ICE hardware.
In this thesis, the second section will focus on the process of integrating ICE hardware circuit and software debugger issued by two ways, our own design version and business suit debugging software support. The examples are not only integrating our LAB¡¦s 32bit microprocessor and ICE hardware, but also verifying software debugger to control ICE circuit by FPGA to prove above two methods are work.

Identifying new technology to improve the effectiveness of IST Otokon's energy management systems / Gerhardus Albertus Combrink.Combrink, Gerhardus Albertus January 2004 (has links)
1ST Otokon, a Pretoria based company delivering energy management systems to the industrial and utility market segments, has shown steady growth since its inception 15 years ago. However, after ailing financial results, all aspects of the business were interrogated. It was doubted whether its energy management system (EMS) offering, ecWIN, was fulfilling the needs of the industry. Therefore this study was needed to identify new technology which could improve the effectiveness of ecWIN.
After doing a thorough literature study on ecWIN, its competitors and the technologies currently utilised, the product was mapped to various technology management models. Deficiencies in the current software development environment were identified, including a lack of manpower and old software development tools.
The empirical study entailed determining the effectiveness of the product through a user survey in the form of a questionnaire. Certain problem areas (e.g. insufficient software testing and a lack of documentation on advanced features) were identified by this survey. The numerous complaints about the slowness of certain reports and lack in user-friendliness were also highlighted.
Also forming part of the literature and empirical study respectively, were the identification and evaluation of new technologies not yet utilised in the ecWIN sphere.
Taking a holistic view of all this information, recommendations were made on how to improve the effectiveness of ecWIN. This was presented in terms of three dimensions:
• Upgrade the current infrastructure over the next 12 months, mainly with new software development tools such as Centura Team Developer 2005, Crystal Reports, etc.
• Improve the cost-effectiveness of ecWIN during 2006 and 2007, typically by utilising GPRS, MMS, WiFi and BlueTooth to retrieve information from meters.
• Utilise a new business model (mainly centred on the cost-effectiveness dimension together with Linux and MySQL) which could allow the company to directly compete with other firms, even in the commercial and residential markets.
A fourth dimension, consisting of technologies that should not be considered for integration with ecWIN at this stage, was also identified (e.g. IPv6, XHTML and Visual Studio .NET).
In a world with rapidly changing technology, this study should not be a once-off process, but should be undertaken regularly to ascertain that the effectiveness of 1ST Otokon's EMS offering is constantly improved through the identification of new technology. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2005.

Making scope explorable in Software Development Environments to reduce defects and support program understandingvon Oldenburg, Tim January 2014 (has links)
Programming language tools help software developers to understand a program and to recognize possible pitfalls. Used with the right knowledge, they can be instrumented to achieve better software quality. However, creating language tools that integrate well into the development environment and workflow is challenging.This thesis utilizes a user-centered design process to identify the needs of professional developers through in-depth interviews, address those needs through a concept, and finally implement and evaluate the concept. Taking 'scope' as an exemplary source of misconceptions in programming, a “Scope Inspector” plug-in for the Atom IDE—targeting experienced JavaScript developers in the open source community—is implemented.

Ambiente integrado de modelagem distribuída para sistemas de informação na internet / Integrated environment for distributed modeling of web information systemsPompermaier, Leandro Bento January 1999 (has links)
O objetivo principal desta dissertação explora alguns aspectos relacionados ao desenvolvimento colaborativo de sistemas de informação na Internet. E apresentado o Editor Diagramático na Internet (EDI), que suporta a especificação colaborativa de aplicações. Este editor utiliza tecnologia e funcionalidade dos hiperdocumentos, oferecendo características como: compartilhamento de informações, colaboração entre vários autores e varias visões dos dados conceituais armazenados. EDI foi implementado utilizando a linguagem de programação Java e projetada de forma genérica para permitir a criação de editores de diferentes notações diagramáticas. Este trabalho propõe a utilização de anotações em documentos de desenvolvimento de sistemas de informação na Internet. Estas anotações auxiliam no desenvolvimento colaborativo de sistemas, tornando o processo mais colaborativo e com um produto resultante de qualidade superior. As anotações estão baseadas em dois tipos de usuários: o usuário proprietário, responsável pela criação do documento, e o usuário colaborador, que inclui anotações nos documentos. Anotações (identificadas por uma especifica cor) podem ser de inclusão, alteração, remoção de conceitos (visões) ou registro de comentários. / The main goal of this work is to explore some issues related to collaborative development of information systems on the Internet. A Diagrammatic Editor on the Internet (EDI) that supports collaborative specification of applications is described. This editor uses hyperdocument technology and funcionalities, offering features such as information sharing, collaboration between several authors, multiple views of the stored conceptual data, among others. EDI was implemented using the Java language, and designed with the purpose of being generic to enable the easy creation of specific editors for different diagrammatic notations. The use of annotations for the joint development of information systems on the Internet is proposed. With these annotations the development process becomes more collaborative and the quality of the final product may increase. Annotations are based on two types of users: the owner, who is an author responsible for the creation of a document, and the collaborator, who makes annotations on those documents. Annotations (identified by one specific colour) can be of inclusion, change and removal of concepts (views), or recording of comments.

Proposta de suporte XML para ambientes de desenvolvimento de sistemas visuais interativos baseados em gramáticas / A XML support propose to development environments of interactive visual systems based on grammarsTelecken, Tiago Lopes January 2008 (has links)
Ambientes de Desenvolvimento Baseados em Gramática (ADBG) utilizam uma rigorosa semântica e sintaxe para prover poderosas ferramentas que são capazes de especificar com precisão as propriedades de um sistema visual interativo. Por intermédio destas ferramentas, os ADBGs auxiliam a edição de gramáticas e a partir destas gramáticas geram o sistema visual interativo especificado. Estes ambientes utilizam componentes dos mais diferentes espaços tecnológicos e esta tese em particular está focalizada no estudo da utilização de componentes da eXtended Markup language (XML) em ADBGs. Componentes XML oferecem inúmeras soluções que visam a interoperabilidade e armazenamento de dados. Porém, apesar de amplamente difundidos a complexidade destes componentes causa uma série de problemas que vão desde o baixo desempenho de processamentos até a inviabilização da implementação de operações mais elaboradas. Com o objetivo de diminuir esta complexidade, a presente tese propõe um conjunto simplificado de componentes XML. O conjunto dos componentes XML propostos e seus relacionamentos formam um framework que pode ser utilizado para se construir ADBGs. Após a definição do framework, o mesmo foi utilizado para se implementar o protótipo de um ADBG. A implementação e uso deste protótipo demonstrou concretamente a viabilidade e aplicabilidade das propostas desta tese. Já para demonstrar a referida diferença de complexidade, os componentes XML do framework proposto foram comparados com os componentes XML dos demais ADBGs. A comparação revelou que os componentes XML das demais abordagens têm entidades adicionais que não estão presentes nos componentes propostos. Este conjunto adicional de entidades comprovou a maior complexidade dos componentes XML utilizados nos demais ADBGs. Adicionalmente, a referida comparação demonstrou que mesmo sendo mais simples os componentes propostos mantêm as mesmas funcionalidades que os componentes atualmente utilizados. / Development Environments Based on Grammar (DEBGs) often rely on rigorous syntax and semantics, which provide powerful tools to fully specify visual interactive systems and its properties. Such environments provide to visual interactive system developers a set of editors to aid the grammar specification. From these grammars specifications the DEBGs can generate the specified visual interactive systems. Such environments can use components from several technological spaces. However this thesis is focused on the application of eXtended Markup language (XML) components in DEBGs. XML components provide many solutions in terms of interoperability and data storing. Despite of its widely application, the complexity of XML components is the cause of problems such as low processing performance and inviability of many implementations. Aiming to decrease such complexity, we propose a set of simplified XML components. The set of proposed XML components and its relationships compose a framework that can be used to develop DEBGs. After the framework specification, the framework was used to implement a DEBG prototype. Such prototype shows the viability and applicability our proposals. We demonstrate the referred complexity difference comparing the XML components proposed in this thesis with the XML components applied in others DEBGs. Basically, the XML component of others DEBGs has all entities of correspondent component proposed in this thesis more a set of extra entities. This set of extra entities demonstrates the greater complexity of other approaches. Additionally, the referred comparison demonstrates that despite of its simplifications, the proposed components have the same functionalities than the current components.
