Dynamic Translator-Based Virtualization

چکیده
Microkernels and virtual machine monitors are both utilized as platforms for running operating systems. Although there are many similarities in their designs and features, they have opposite advantages and drawbacks. A microkernel based system is highly portable. However, the interface it exposes is inflexible and incompatible with other real hardware interfaces. In contrast, a virtual machine monitor interface is identical to a specific real hardware interface. However, the implementation of virtual machine monitors highly depends on processor architectures and specific hardwares. In this paper, we present a new model of virtual machine monitor, a flexible dynamic translator constructed on a portable microkernel. Our model offers both high portability and compatibility. Moreover, its flexible interface could be reconfigured to support various types of hardware interfaces. The results of the evaluation show that the performance of our prototype system is unsatisfactory, so we propose some techniques to improve its performance as future work.

Virtualization is emerging as an important technology in future systems, providing an extra layer of abstraction between the hardware and operating system. Previous work on virtualization has focused on the partitioning, isolation, and encapsulation features of virtual machines and their use for different applications, but mainly in the context of a specific processor architecture. In this pape...
متن کاملLow-Complexity Dynamic Translation in VDebug
Machine-level dynamic binary translation has been used in applications ranging from debugging, performance analysis, and security policy enforcement to full machine virtualization. Most implementations are optimized for performance rather that simplicity: they translate to an internal intermediate form before generating target code. While an intermediate form greatly assists certain types of co...

To facilitate the development of the dynamically partially reconfigurable system (DPRS), we propose a model-based platform-specific co-design (MPC) methodology for DPRS with hardware virtualization and preemption. For DPRS analysis and validation, a model-based verification and estimation framework is proposed to make model-driven architecture (MDA) more realistic and applicable to the DPRS des...
متن کاملA universal molecular translator for non-nucleic acid targets that enables dynamic DNA assemblies and logic operations.
A universal molecular translator based on the target-triggered DNA strand displacement was developed, which was able to convert various kinds of non-nucleic acid targets into a unique output DNA. This translation strategy was successfully applied in directing dynamic DNA assemblies and in realizing three-input logic gate operations.
