Firstly, the basic concept of software/hardware co-design and the present research situation worldwide is introduced, the techniques are also discussed separately in the thesis, which is in the system description stage, system architecture design stage, hardware/software design and implementation stage. Secondly, combined with three representative methods of hardware/software co-design systems: POLIS、VULCAN and CORSAIR, the main steps of co-design are studied and analyzed including system description, hardware/software partitioning and hardware/software implementation-synthesis, and some new ideas are given here. Thirdly, UML and modeling technology of embedded systems using UML are described clearly, a handheld terminals is a good example for this, furthermore, the algorithm of how to convert the UML diagram into SystemC codes is mainly concerned on in this thesis. Fourthly, the basic concept of SystemC is described, and the SystemC Modeling platform and simulation mechanism are analyzed, software/hardware co-design methods using SystemC are discussed. Finally, by applying co-design ideas using UML and SystemC, software/hardware co-design system using UML and SystemC is preparatorily implemented, which is to establish a development environment for designing embedded system.
