Abstract:
A multi-operating-system (multi-OS) configuration method comprising the steps of:assigning a first hardware resource to a first OS and a second hardware resource to a second OS fixedly and exclusively when said first OS is set up, wherein said first and second OSs are executed independently of each other by a single processor; storing an interrupt process program in a common area of a physical memory used by said first and second OSs, said interrupt process program accepting interrupts from said single processor, wherein said interrupt process program executes independently of operation of said first and second OSs; said interrupt process program indicating an execution of an interrupt to one of said first and second OSs based on interrupts accepted; and running one of said first and second OSs independently of the other of said first and second OSs without emulation and software for a privilege instruction to be executed by each of said first and second OSs.
