A utilização de um sistema multiprocessador heterogêneo tornou-se um paradigma de design popular para construir um sistema embarcado a um custo barato e em um curto tempo de desenvolvimento. Um problema de confiabilidade para sistemas embarcados, que é a vulnerabilidade a perturbações de eventos únicos (SEUs), tornou-se um motivo de preocupação à medida que a tecnologia avança. Este artigo discute a confiabilidade inerente a multiprocessadores heterogêneos e propõe escalonamento de tarefas para minimizar a vulnerabilidade SEU deles. Este artigo mostra experimentalmente que o aumento do desempenho de um núcleo de CPU deteriora sua confiabilidade. Com base na observação experimental, propomos escalonamento de tarefas para reduzir a vulnerabilidade SEU de um sistema multiprocessador heterogêneo. Os resultados experimentais demonstram que nossa técnica de agendamento de tarefas pode reduzir grande parte da vulnerabilidade do SEU sob restrições de tempo real.

Abstract: Utilizing a heterogeneous multiprocessor system has become a popular design paradigm to build an embedded system at a cheap cost within short development time. A reliability issue for embedded systems, which is vulnerability to single event upsets (SEUs), has become a matter of concern as technology proceeds. This paper discusses reliability inherent in heterogeneous multiprocessors and proposes task scheduling for minimizing SEU vulnerability of them. This paper experimentally shows that increasing performance of a CPU core deteriorates its reliability. Based on the experimental observation, we propose task scheduling for reducing SEU vulnerability of a heterogeneous multiprocessor system. The experimental results demonstrate that our task scheduling technique can reduce much of SEU vulnerability under real-time constraints.
