    摘要: A system, method and computer program product for enhancing a real-time operating system (RTOS) with functionality normally associated with a general purpose operating system (GPOS). A hypervisor that is adapted to perform a real-time scheduling function supports concurrent execution of an RTOS and a GPOS on a system of shared hardware resources. The RTOS or its applications can utilize services provided by the GPOS. Such services may include one or more of file system organization, network communication, network management, database management, security, user-interface support and others. To enhance operational robustness and security, the hypervisor can be placed in read-only storage while maintaining the ability to update scheduling mechanisms. A programmable policy manager that is maintained in read-write storage can be used to dictate scheduling policy changes to the hypervisor as required to accommodate current needs.
