Sistema operacional embarcado eCos com suporte a SMP para o processador Nios II

Abstract. The objective of this work consists on the exploration of the resources offered by FPGAs for the development of a multiprocessed platform with the purpose of parallel execution of tasks for robotic purpose. In this way, the eCos operating system was modified, with the addition of new characteristics to sup-port of the Symmetric Multiprocessing model, using three soft-Core Altera Nios II processors. This platform was analyzed and validated through the execution of parallel algorithms, emphasizing aspects of performance and flexibility com-pared to other architectures. Resumo. O propósito deste trabalho consiste no aproveitamento dos recursos oferecidos pela FPGA para o desenvolvimento de uma plataforma multipro-cessada com a finalidade de execução paralela de tarefas para a robótica. Deste modo, o sistema operacional eCos foi modificado, com a agregação de novas funcionalidades, para permitir o suporte do modelo Multiprocessa
