No. of bitstreams: 1 DissDSC.pdf: 4212155 bytes, checksum: 09fae7e4670f0c6249beccb0e16122c8 (MD5) Previous issue date: 2017-02-01 / Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) / The advent of multicore processors represented a major advance in the performance of parallel computing. Embedded systems following this trend have improved the computing power available for real-time systems, enabling the GNU/Linux development chain. Consolidated to more than twenty years in the Linux environment. In order to emulate the RTXC kernel, an API-RTXC-Linux was written in C and obtained deterministic results as well as homogeneous distribution for the response time of implemented calls, being possible its use for real-time applications. / O advento dos processadores multicore representou um grande avanço no desempenho da computação paralela. Os sistemas embarcados seguindo essa tendência, melhoraram o poder computacional disponível para sistemas de tempo real, possibilitando a utilização da cadeia de desenvolvimento GNU/Linux. Consolidado a mais de vinte anos no mercado, o RTOS RTXC da Quadros Systems, foi escolhido para ser emulado no ambiente Linux. Com o objetivo de se emular o kernel RTXC, a API-RTXC-Linux foi escrita em C e obteve resultados determinísticos além de distribuição homogênea para tempo de resposta das chamas implementadas, sendo possível seu uso para aplicações de tempo real.
