In recent years, desktop virtualization trends to be a new extension of virtualization framework. The existing desktop virtualization systems suffer performance degradation in terms of response time and video quality. However, previous remote access approaches are designed for standalone architectures and require semantic information which is not transparent to OS. So they are not feasible in desktop...
Utilizing virtualization technology to combine real-time operating system(RTOS)and off-the-shelf time-sharing general purpose operating system (GPOS)is attracting much more interest recently.Such combination has the potential to provide a large application base,and to guarantee timely deterministic response to real-time applications,yet there is no convincible experimental result about its real-time...
System virtualization, which provides good isolation, is now widely used in server consolidation. Meanwhile, one of the hot topics in this field is to extend virtualization for embedded systems. However, current popular virtualization platforms do not support real-time operating systems such as embedded Linux well because the platform is not real-time ware, which will bring low-performance I/O and...
In Recent years embedded world has been undergoing a shift from traditional single-core processors to processors with multiple cores. However, this shift poses a challenge of adapting legacy uniprocessor-oriented real-time operating system (RTOS) to exploit the capability of multi-core processor. In addition, some embedded systems are inevitably going towards the direction of integrating real-time...
Dynamic binary translation (DBT) is a well known software technology that enables seamless cross-ISA execution. Unfortunately, many malicious programs that may lead to unauthorized access can run easily and unrestrictedly under the DBT system. Because these malicious programs must go through the system call interface to take malicious action, system call interposition has become a widely used technique...
