PURPOSE:To improve the performance of an information processor by invalidating a bus occupation request signal once in a DAM controlling part during data processing in an auxiliary storage part to actuate a central processing part. CONSTITUTION:An auxiliary storage connected to a central control part, a main storage part and a buffer memory and the DAM controlling part 8 of a peripheral control part are connected to a bus line 9 of an information device. A memory address register 12, a transfer number data address register 13, a bus controlling counter 14, and a DAM inside controlling part 15 are connected to the bus line 9 and an inside controlling bus 16 of the controlling part 8. It is defined that the counting capacity of the counter 14 is the same as the data capacity of one sector of the auxiliary storage. The inside controlling part 15 of the controlling part 8 invalidates a bus occupation request signal once, subtracts the contents of the counter, and when the subtracted result coincides with the value of the auxiliary storage equal to an initial value, actuate a central processing part, improving the processing efficiency of the titled device. |
