INTERRUPTION HANDLING SYSTEM

An interruption processing system enables a basic CPU resource using process to be executed asynchronously, enabling an interruption handler to be easily created. Interruption handling of the basic CPU resource using process interruption handler to be executed asynchronously enables corresponding interruption handler process is terminated for a CPU resource using process dependent interruption factor. The interruption processing system comprises a queuing unit for determining whether an instruction stored in an instruction buffer designates a synchronous process or an asynchronous process and for queuing the instruction when it is an asynchronous process. When more than one asynchronous process which has been queued is terminated unprocessed or with exceptions in the case where an interruption is generated in a synchronous processing unit or an asynchronous processing unit or an interruption from the outside of a CPU is detected, contents and termination methods of all asynchronous processes terminated unprocessed or with exceptions at the time of the generation of the interruption are displayed in order to resume the program prior to the generation of the interruption.
