Pré-estudo de aparelho portátil detector de radiação.

Abstract

The quantity of nuclear material existing in the world is constantly increasing. A fundamental objective for global security is to minimize the nuclear proliferation risks associated with this increase. This document present the electronic part of the "Kappa"project: a handheld device for detection and identification of radiation. We discuss the new technologies in the field of embedded electronic systems and we analyze the ARM embedded processors and solutions for components integration. In order to reduce the time-tomarket and development costs, the device uses the "System on Module"Torpedo LogicPD AM18x that integrates a T I AM1808 processor, 128MB of Mobile DDR memory, 8 MB NOR Flash memory, and a power management module. The next step of the project focuses on the estimation of the performances and power consumption of the system along with its software environment using an Development Kit.
