NEC Corporation has announced that it has succeeded in the development of multiprocessor virtualisation technology.
The company says that the new technology enables the flexible and secure installation of a wide variety of application software on electronic devices in accordance with user needs, without causing any harm to the operation of the pre-installed application software for basic functions. This technology is aimed at making a variety of devices such as information systems more multi-functional.
The new multiprocessor virtualisation technology is based on NEC's proprietary multiprocessor technology for embedded systems. It separates the application software for basic functions, which was initially installed on the intended device, and groups of application software that have been added at a later date by the user through the allocation of both to different processors.
These processors are then further separated into virtual processors according to the characteristics of the application software. Virtual separation succeeds in avoiding interference among the groups of application software, thereby allowing a greater number of diverse groups of application software to be flexibly and securely installed on embedded devices.
Such an approach is also designed to enable a high level of security as the hardware monitors the access to the memory or inter-processor communication among the virtual processors. This, says NEC, results in significantly enhanced system performance as compared with conventional methods, which only realise virtual processors with software. Furthermore, switching time between application software has been cut by 50%.
NEC says that its multiprocessor virtualisation technology allows multiple independent processors to be virtually built on top of actual processors, allowing an increase in groups of application software for installation, while eliminating interference among the added groups of software.
