25. Projeto e implementação de circuitos classificadores digitais com controle da generalização baseado na regra do vizinho-mais-próximo modificada
This work aims at the implementation of classifying binary patterns with digital circuits in order to get a embedded system with the following features: portability, on-line training, operating in real time and with capacity of generalization. The proposed method makes use of training data filtering (or selection) before digital circuit synthesis. It is prop

26. Uma metodologia de projetos para circuitos com reconfiguração dinâmica de hardware aplicada a support vector machines. / A design methodology for circuits with dynamic reconfiguration of hardware applied to support vector machines.
Systems based on general-purpose processors are characterized by a flexibility to design changes, although with a computational performance below those based on optimized dedicated circuits. The implementation of algorithms in reconfigurable devices, known as Field Programmable Gate Arrays, FPGAs, offers a solution with a trade-off between the processors fle

27. Phoenix um framework para trabalhos em síntese de alto nível de circuitos digitais
Este trabalho descreve o desenvolvimento de um framework de código aberto para síntese de circuitos digitais, para uso em projetos de hardware/software co-design. O framework consiste de um compilador que aceita ANSI C como código fonte e que permite a construção de um dado sistema e sua execução em hardware. Este compilador, intitulado Phoenix, permi

28. Uma abordagem para a modelagem de sistemas digitais
Digital system design has reached a high degree of complexity that prevents its realization without CAD tools. The starting point of such tools consists on a conceptual view of the intended system (given by one or more conceptual models), which is captured for computational handling by one or more specification languages. Several of such languages were devel

33. Neuromorphic hardware databases for exploring structure-function relationships in the brain.
Neuromorphic hardware is the term used to describe full custom-designed integrated circuits, or silicon 'chips', that are the product of neuromorphic engineering--a methodology for the synthesis of biologically inspired elements and systems, such as individual neurons, retinae, cochleas, oculomotor systems and central pattern generators. We focus on the impl
