METHOD OF MANAGING SOFTWARE IMAGES, COMPUTER PROGRAM, AND SYSTEM (MANAGEMENT OF MULTIPLE SOFTWARE IMAGES WITH SHARED MEMORY BLOCKS)

PROBLEM TO BE SOLVED: To provide a solution to manage a plurality of software images.SOLUTION: A single version of each memory block of at least a subset of all of the software images is stored into a corresponding memory location. Each memory block is associated with the memory location storing the memory block. The memory blocks stored in boot locations of a current software image are relocated. The boot locations of each software image are the memory locations having the memory addresses equal to the image addresses of boot blocks of the software image, and the boot blocks include the memory blocks required to boot the data processing entity up to load an access function adapted to access the memory blocks of the software image. The boot blocks of the current software image are stored into the corresponding boot locations.
