An OBSM Method for Real Time Embedded System

The traditional OBSM method in spacecraft and other real time embedded system is to re-compile the whole system after source code modification, and then reboot the target machine with the new version software. This hurts the availability of the system. Most of the new methods are based software or hardware redundancy. To reduce the cost and make the OBSM more conveniently, we classify OBSM, and patch the target system with different method according to different OBSM type, so the new solution can reduce the cost
