摘要： A computer apparatus (100) includes an OS execution unit (120), an OS-dependent interrupt processing unit (110), and an OS-independent interrupt processing unit (130). When an OS-independent interrupt (201) due to a state of a device (200) occurs, the OS-independent interrupt processing unit (130) determines whether or not to initiate a task (145). When the task (145) is to be initiated, the OS-independent interrupt processing unit (130) turns on the flag (141) and causes the OS execution unit (120) to generate an OS-dependent interrupt (202). When the OS-dependent interrupt (202) is generated, the OS-dependent interrupt processing unit (110) determines whether or not the flag (141) is on, and when the flag (141) is on, initiates the task (145) and turns off the flag (141).

摘要： An information processing apparatus (100) includes a validity verification unit (101). The validity verification unit (101) verifies validity of startup software by comparing verification subject data which is data for verification calculated based on data stored in a storage place indicated in startup record data indicating the storage place where the startup software executed at startup of the information processing apparatus (100) is to be stored, and which is data for verification calculated at the startup of the information processing apparatus (100), with comparison data which is data for verification calculated before the startup of the information processing apparatus (100) based on the startup software, and which is data for verification used as a comparison subject of the verification subject data.

摘要： A management domain unit is connected, via an independent virtual network (95) using a hypervisor unit, to a separate management domain unit (B) (10B) of a separate electronic control unit ECU (B) (1) having the separate management domain unit (B) (10B) and a separate basic domain unit (A) (50B) which substitutes for a basic domain unit. When an abnormality of the basic domain unit is detected, the management domain unit halts operation of the basic domain unit, and causes the separate management domain unit (B) (10B) possessed by the separate electronic control unit ECU (B) (1) to start operation of the separate basic domain unit (A) (50B).
