[pt] Este trabalho consiste na apresentação das rotinas de testes que forma desenvolvidas visando a verificação do funcionamento do microcomputador desenvolvido no Grupo de Eletrônica da PUC (GELUC): o MICRO-02 Essas rotinas de testes constam de microprogramas e também de programas realizados com o auxílio do repertório de instruções do microprocessador central (CPU - 8008) do microcomputador. Elas visam apenas o teste funcional do sistema não se preocupando com a localização da falha. Entretanto, através dos resultados de partes já testadas, pode-se tirar conclusões que permitam um grau de localização mais preciso da falha. / [en] This work consists of a presentation of test routines that were developed taking into account the verification of the Microcomputer´r functioning developed by GRUPO DE ELETRÔNICA DA PUC (GELUC): the MICRO-02. These test routines consist of microprograming and also of programs developed with the aid of the instructions report of the microcomputer´r central microprocessor (CPU - 8008). They only intend the functional test of the system, and do not take into account the localization of the failure. However, through the results of parts which have already been tested, one can have conclusions that allow a more precise degree of localozation of the failure.

[pt] O rastreio automático de alvos com radares de vigilância implica basicamente em quatro fases distintas: a extração de sinais (ecos) radar em áreas delimitadas previamente estabelecidas no campo de vídeo radar; a detecção por limiar e por integração binária de alvos num meio ruidoso de modo a satisfazer uma determinada probabilidade de falsos alarmes; a determinação das coordenadas geográficas dos alvos detectados; e a predição de novas áreas onde, provavelmente, estarão os alvos durante a próxima rotação da antena do radar. O presente trabalho consiste no desenvolvimento de um sistema de rastreio automático, controlado por um microcomputador, capaz de executar as quatro fases descritas. / [en] The automatic tracking of targets using surveillance radars leads basically to four distinct phases: the extraction of radar signals (echoes) within areas previoisly established in the radar display; the detection of targets in a noisy medium by threshold and improved by binary integration in order to satisfy a fixed probability of false alarms; the comutation of geographic coordinates of detected targets; and the prediction of other areas where, probably, will be the targets during the following scanning of the radar antenna. This work consists in the development of an automatic tracking system, controlled by a microcomputer, capable of doing the four phases described above.

The first chapter of the master´s thesis deals with the analysis of problems indesigning of devices, which include individual steps of the designing of the device and the choice of the most suitable option. It deals with the analysis of the proposed assignment and requirements for this device, analysis of battery management chip that the device should be able to communicate with, analysis of the I2C/SMBus communication protocol which is used for communication between the device with the battery management chips and possibilities of communication of the device with computer. The second chapter deals with the communications via USB bus and the description of this communication. The next step is dedicated to the selection of a programmable microprocessor Atmel AT90USB1287, describes his pin configuration, the possibilities, describes the way of USB interface connection, the method of the I2C/SMBus interface connection and its protection. In the last part of the this chapter the thesis describes Atmel microcontroller programming, specifically describes how to program I2C/SMBus communication, USB communication and how to write a program to the microprocessor. The third chapter of the thesis deals with the design of a single device, and components like a scheme of the connection and the concept of functional realization of the communication with device. The fourth chapter deals with the development of the device itself. Describes the parts of final involvement and describes the parts of the final program for microprocessor, such as communication with SMBus device and communication through the USB bus. The fifth chapter is devoted to the development of communication applications in Java. This section describes the different elements of applications such as communication with USB devices, data storage and open for viewing. The last chapter presents the final device and the final communication application.

Microprocessor-Based Closed-Loop Motor Control. A dedicated microprocessor control system was built from chip level using the Motorola M6800 family. The system has a keyboard and the interfaces for four LED displays, a phototransistor and a digital-to-analog converter. The system accepts key input in RPM and drives the motor at the input RPM with display of the real RPM updated approximately every second.

According to references, testing and verification of a hardware circuit project occupy about 60%˜70% of project time. Now that product cycle time is decreasing, verification methodology is an important parameter for effective and successful completion of a design project. Enhanced processor functions also make verification conditions more difficult. In this thesis the processor SYS32IME III, which is constructed based on architecture of ARM 1022E, is verified by using V5TE instruction set. This thesis focus on processor verification flow and others to help verification method. The verification language that is used to help generate testbench are described in this paper. Also, corner cases are generated, producing test cases that may be reused in different verification environments. Lastly, errors from CPU architecture, verification environments, interface wrapper and instruction set simulator were found in different verification environment and fixed. To conclude the study, insertion of self-implemented RTL monitor circuit into CPU architecture supply verification information about testbench¡¦s coverage of functional verification.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper discusses the design and implementation of a microcomputer system that functions as the central processing unit for performing servo system control, tracking mode determination, operator interface, switching, and logic operations. The computer hardware consists of VMEbus compatible boards that include a Motorola 32-bit MC68020 microprocessor-based CPU board, and a variety of interface boards. The computer is connected to the Radio Frequency system, Antenna Control Unit, azimuth and elevation servo systems, and other systems of the Advanced Transportable Telemetry Acquisition System (TTAS-A) through extensive serial, analog, and digital input/output interfacing. The software platform consists of a commercially-acquired real-time multi-tasking operating system, and in-house developed device drivers and tracking system software. The operating system kernel is written in assembly language, while the application software is written using the C programming language. To enhance the operation of the TTAS-A, software was also developed to provide color graphics, CRT menus, printer listings, interactive real-time hardware/software diagnostics, and a GPIB (IEEE-488 bus) interface for Automated Testing System support.
