Abstract
PURPOSE: To avoid the system down dependent upon the trouble of memory banks by using two memory banks respectively to double the save area for an executing PSW and an interrupt processing PSW and providing and doubling a memory trouble processing program in two memory banks.
CONSTITUTION: When a memory trouble is reported to CPU 14 through data path 15, contents of register 13 are stored in old PAW 7 through data path 15, control unit 21 and data path 16 if the faulty memory bank is other than memory banks 2 and 4, and new PSW 8 is stored in register 13, thereby executing a memory trouble processing program in memory bank 4. If the faulty memory bank is bank 2 or bank 4, contents of register 13 are stored in old PSW 9 through control unit 22, and new PSW 10 is stored in register 13, thereby executing a memory trouble processing program in memory bank 5.
