By providing a Virtual Resource Manager (VRM) to control hardware and provide a high-level interface for multiple virtual machines, multiple concurrent applications and operating systems in virtual machines are supported by controlling the sharing of system resources. Using a hardware base consisting of a high-speed Reduced Instruction Set Computer (RISC) microcomputer with hardware assist for virtual memory management and an IBM PC AT (Advanced Technology) compatible I/O bus, it is desirable to provide the following features: 1. Provide a high-level machine interface, which simplifies the development and implementation of operating systems and their applications. 2. Maximize performance to support real-time process control-type applications. 3.
