PURPOSE:To simplify a program, by constituting a computer system so that an address of each apparatus or device can be changed freely by software. CONSTITUTION:A disk 7 and 8 are connected to a CPU1 and 2, respectively and a disk control device 3 and 4 are held in common by each CPU1 and 2. The CPU1 and 2 are constituted so as to be controlled respectively by addresses 5b, 5c, 6b and 6c. Although contents of memory parts 5a, 6a of this system are fixed by hardware, contents of the memory prts 5b, 6b, 5c and 6c are read and written freely by software. In this way, when a new disk is accessed, the time required for regeneration of a program is shortened extremely, and a program is simplified, without being aware of a change of the contents of the memory parts 5b, 6b, 5c and 6c. |
