英文摘要： Computer virtualization technology, which decouples the hardware and the software that runs on it, implements the construction of the virtual image of the computing system on demand. Virtualization presents new computing mechanism and computing pattern. As multi-core and heterogeneousness is the trend of the computing systems, we will study on the Co-designed Virtual Machine (Co-VM) based on heterogeneous multi-core architecture. By combining dynamic binary translation which implements the compatibility of heterogeneous architecture with the VMM which supports multiple virtual machines environment, we will implement the virtualization of the heterogeneous multi-core computing system. We will improve the performance of the virtualized system through hardware and software co-design technique. The main issues we focus on include: analysis of the working mechanism of the virtualized computing system and the Co-VM, support theory of the Co-VM, the architecture of the Co-VM which supports multiple virtual machine environment, efficient dynamic binary translation technique, hardware and software co-design which can greatly improves the efficiency of the Co-VM, parallelization of application's target codes on multi-core platform, the architecture of the heterogeneous multi-core prosessor which supports virtualization.
