Abstract
A method and apparatus for relocating a storage such that a physical address area of the storage, which is allocated to an absolute address area, is replaced with a new physical address area. This relocation process is performed with a Floating Address Register for translating an absolute address into a physical address in a hierarchy storage system including a main storage and a store-in cache memory, thereby reducing a stopping time of the main storage during the relocation process. According to the method, data of the area of object physical addresses to be relocated is fetched into a block of the cache memory, and then the new physical addresses of the storage are allocated to the absolute address to which the old physical addresses have been allocated.
