Abstract
An operating system (OS) of a data processor physically relocates segments of memory containing real addresses used by the operating system itself, which addresses must remain unaltered within the system. The system identifies a memory bank containing a source segment having such real addresses, quiesces the OS, and copies the source segment to a target memory module. A register identifying the real addresses stored in the target module is renamed to the addresses of source segment, and the OS resumes executing normal tasks. The data processing system may have multiple system modules each having processors, memory, and/or other components.
