INFORMATION PROCESSING APPARATUS

摘要

A memory stores therein a program status word containing an address of data that is to be read when an interrupt process is executed a processor determines whether or not the program status word stored in the memory is available, controls the memory to stores a determination result in the memory in association with the program status word, acquires the program status word and the determination result from the memory when the interrupt process occurs, and reads data on the basis of the address contained in the acquired program status word when the acquired determination result indicates that the program status word is available.

主权项

1. An information processing apparatus comprising:
a memory configured to store therein a program status word containing an address of data that is to be read when an interrupt process is executed; a first processor configured to determine whether or not the program status word stored in the memory is available, and to control the memory to store a determination result in association with the program status word; and a second processor configured to acquire the program status word and the determination result from the memory when the interrupt process occurs, and to read data on the basis of the address contained in the acquired program status word when the acquired determination result indicates that the program status word is available.
