Abstract

A method of enabling multiple different operating systems to run concurrently on the same computer, comprising selecting a first operating system to have a relatively high priority (the realtime operating system, such as C5); selecting at least one secondary operating system to have a relatively lower priority (the general purpose operating system, such as Linux); providing a common program (a hardware resource dispatcher similar to a nanokemel) arranged to switch between said operating systems under predetermined conditions; and providing modifications to said first and second operating systems to allow them to be controlled by said common program.

Description

Technical field [0001] The present invention relates to operating systems. More specifically, the present invention relates to a system, method, and computer program for simultaneously running multiple operating systems. Background technique [0002] For some computer programs, the key is: the steps in the program should be performed within a limited time period or at a limited time. Examples of such programs are control programs for operating mobile phones, or control programs for operating private exchanges (PBX) or cellular base stations. Generally speaking, this kind of program must respond to the external event or state change in a coherent manner at a certain moment or within a certain time after the external event or state change. This is called "real-time" operation. [0003] However, for many other programs, the time it takes to execute the program is not critical. This applies to most public computer programs, including spreadsheet programs, word processing programs, sa...
