Abstract

PURPOSE: To improve system integrity by holding interruption information in hardware where access can not be attained by an user.
CONSTITUTION: Interruption information needed for restart operation is retained in area 5' of cash memory 2 in central processor 1 or area 5" of control memory 3. Further, fixed task iD is added so as to make clear which task the retained interruption processing, the OS program selects a task to be executed next from control information including PSWs that are standing by in the memory for the OS program. When an instruction indicated by an instruction address part in PSW is a restart instruction, the task iD storage area of the corresponding PSW register is checked and when it is stored, the information standing by in the stand-by area is restored in various registers in the processor.
