Information processing unit, and exception processing method for application-specific instruction

摘要

The control section of an information processing apparatus is set to a mode of execution of an application- specific operation. When an interruption processing program has been started after interrupting the execution of a program, a context is saved, and thereafter it is confirmed whether the operation mode has been set to a state that an operation exception that occurs during the execution of an application- specific operation instruction is detected or not. When an operation exception has been detected, an application- specific operation exception processing is carried out. Then, the context is restored, and the processing returns from the interruption.
