Hard real-time performances in multiprocessor-embedded systems using ASMP-Linux

Multiprocessor systems, especially those based on multicore or multithreaded processors, and new operating system architectures can satisfy the ever increasing computational requirements of embedded systems.ASMP-LINUX is a modified, high responsiveness, open-source hard real-time operating system for multiprocessorsystems capable of providing high real-time performance while maintaining the code simple and not impacting on theperformances of the rest of the system. Moreover, ASMP-LINUX does not require code changing or application recompiling/relinking.In order to assess the performances of ASMP-LINUX, benchmarks have been performed on several hardware platformsand configurations.
