Previous issue date: 2015-05-29 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Esta Tese tem como objetivo desenvolver e implementar uma arquitetura para
suporte a sistemas de Hardware Auton?micos, capaz de gerenciar o hardware em
opera??o em dispositivos reconfigur?veis. A arquitetura proposta implementa
mecanismos para manipula??o, gera??o e comunica??o de arquiteturas de
hardware, usando a metodologia de Reposit?rio Ativo orientado a Contexto. A
solu??o consiste no desenvolvimento de uma arquitetura de Hardware-Software
denominada Autonomic Hardware Manager, que cont?m um Reposit?rio Ativo de
Componentes de Hardware. Usando o reposit?rio, a arquitetura se encarregar? de
gerenciar os sistemas embarcados conectados durante sua opera??o, possibilitando
a implementa??o de caracter?sticas auton?micas como auto-gerenciamento, autootimiza??o,
auto-descri??o e auto-configura??o. A arquitetura proposta contempla
tamb?m um metamodelo para representa??o do Contexto de Opera??o de sistemas
de hardware. Esse metamodelo servir? de base para o desenvolvimento dos
m?dulos de sensibilidade ao contexto, previstos na arquitetura do reposit?rio ativo.
Para fins de demonstra??o do funcionamento da arquitetura proposta, experimentos
foram realizados com vistas a comprovar as hip?teses de pesquisa e alcan?ar cada
objetivo desta tese. Tr?s experimentos foram planejados e executados: o Hardware
Reconfigurable Filter, que consiste em uma aplica??o que implementa Filtro Digitais
atrav?s de hardware reconfigur?vel; o Autonomic Image Segmentation Filter, que
apresenta o projeto e implementa??o de uma aplica??o auton?mica de segmenta??o
de processamento de imagens; por fim, o Autonomic Auto Pilot aplica??o que
consiste de um piloto autom?tico para ve?culos a?reos n?o tripulados. Neste
trabalho, a arquitetura das aplica??es foi organizada em m?dulos, de acordo com as
suas funcionalidades. Alguns destes m?dulos foram reimplementados em HDL e
sintetizados em hardware. Outros m?dulos foram mantidos em software. Em
seguida, a aplica??es s?o integradas com o reposit?rio AHM para possibilitar a sua
adapta??o aos diferentes contextos de opera??o, tornando-as auton?micas. / This Thesis main objective is to implement a supporting architecture to
Autonomic Hardware systems, capable of manage the hardware running in
reconfigurable devices. The proposed architecture implements manipulation,
generation and communication functionalities, using the Context Oriented Active
Repository approach. The solution consists in a Hardware-Software based
architecture called "Autonomic Hardware Manager (AHM)" that contains an Active
Repository of Hardware Components. Using the repository the architecture will be
able to manage the connected systems at run time allowing the implementation of
autonomic features such as self-management, self-optimization, self-description and
self-configuration. The proposed architecture also contains a meta-model that allows
the representation of the Operating Context for hardware systems. This meta-model
will be used as basis to the context sensing modules, that are needed in the Active
Repository architecture. In order to demonstrate the proposed architecture
functionalities, experiments were proposed and implemented in order to proof the
Thesis hypothesis and achieved objectives. Three experiments were planned and
implemented: the Hardware Reconfigurable Filter, that consists of an application that
implements Digital Filters using reconfigurable hardware; the Autonomic Image
Segmentation Filter, that shows the project and implementation of an image
processing autonomic application; finally, the Autonomic Autopilot application that
consist of an auto pilot to unmanned aerial vehicles. In this work, the applications
architectures were organized in modules, according their functionalities. Some
modules were implemented using HDL and synthesized in hardware. Other modules
were implemented kept in software. After that, applications were integrated to the
AHM to allow their adaptation to different Operating Context, making them
autonomic.
