Abstract
Even if each processor core uses the same logical address, a processing-target program corresponding to each processor core can be selected. A logical address of multiple address mapping tables is set to a same logical address in correspondence with an embedded OS program or a RAID management program, and a physical address is set to a different physical address in correspondence with the actual storage destination of an embedded OS program or a RAID management program. Each processor core, on start-up, uses a self address mapping table to execute address mapping processing with each processor core based on the same logical address, selects an embedded OS program or a RAID management program according to the physical address obtained in the address mapping processing, and executes processing according to the selected program.
