In this paper, we propose a virtualization architecture for the multi-core embedded system to provide more system reliability and security while maintaining the same performance without introducing additional special hardware supports or having to implement complex protection mechanism in the virtualization layer. Virtualization has been widely used in embedded systems, especially in consumer electronics,...
A virtualization layer makes it possible to compose multiple functionalities on a multi-core processor with minimum modifications of OS kernels and applications. A multi-core processor is a good candidate to compose various software independently developed for dedicated processors into one multi-core processor to reduce both the hardware and development cost. In this paper, we present SPUMONE, which...
Currently, for embedded systems, the complexity of the software is rapidly increasing due to the advance in the fields of multimedia and network. It is difficult to find the cause of problems. Especially, when the causes of problems are buried in the kernel layer, finding them from application's layer is not easy. One reason of the difficulties comes from that there are not effective tools and functions...
Recently, the engineering cost of embedded systems is rapidly increasing due to growing sophistication of services. To deal with the problem, hybrid operating system environments have been proposed. This enables to run a RTOS and a general purpose OS concurrently and to reuse software resources on both of them. This approach is efficient in reducing engineering costs. We reconfigured the requirement...
The emergence of functional embedded systems such as cell-phones and digital appliances brought up a new issue, building a system supporting both real-time and rich services. One of the solutions is leveraging a hypervisor to integrate an RTOS and a commodity OS into a single device. However, this approach induces the limitation of application deployment; all the high priority tasks should reside...
