英文摘要： Heterogeneous multi-core systems will unavoidably become the mainstream architecture of embedded systems, for its advantages at performance, flexibility, and energy efficiency. Research on efficiently exploiting the huge amount of hardware resources in embedded heterogeneous multi-core systems, and the parallelism of application programs, to enhance performance of the whole system, has become very popular. This research is focused on the automatic parallelization of applications for embedded heterogeneous multi-core systems. Data intensive research methods will be exploited to help construct modeling method for hardware resources in heterogeneous multi-core systems, and to help design paralleled task dividing, scheduling and mapping algorithms. Researches on techniques that can enhance the real-time characteristic and the parallelism of applications will also be included in this work. Those algorithms and techniques will be implemented based on open source compiler. The construction of the automatic parallelization platform will largely enhance the design efficiency, retargetablity, and flexibility of parallel applications for embedded heterogeneous multi-core systems.
