An interrupt processing system capable of asynchronous operation of basic CPU resources to be used with an interrupt handler. Interrupt handlers for use in the processing system are easy to prepare. In this system, a program, suspended by a resource-dependent interrupt, is resumed after the interrupt is completed. The system comprises queuing means for judging whether the instruction stored in an instruction buffer requires synchronous processing or asynchronous processing and queuing the instruction if it requires the asynchronous processing. When an interrupt occurs in a synchronous or asynchronous processing section or outside the CPU, queued asynchronous processes may end in incompletion or may cause exceptions. Therefore, the system further includes means for informing the program, at the occurrence of an interrupt, about the contents (unprocessed jobs, or types of exceptions) and method of termination of all the processing that has not been completed or caused exceptions. Thus, the interrupt program is resumed. |
