Abstract

PURPOSE: To make it possible to efficiently execute the information processing, by saving all the necessary data for recovery of overrun of the interruption, and reexecution of the instruction, in the common buffer register, and making its buffer capacity necessary minimum.
CONSTITUTION: The data saving buffer register 5 is used in common for saving the data for reexecution of the instruction, and recovery of the interruption overrun. A saving data is transmitted from the arithmetic unit 2 through the signal line 105, and a read data for recovery is sent out from the signal line 106. To this register 5, a write pointer and a write pulse are sent through the signal line 113 from the data saving control part 4. That is to say, the information processing can be executed efficiently by saving the necessary data for recovery of the interruption overrun and reexecution of the instruction, in the common register 5, and making its buffer capacity necessary minimum.
