Abstract

PURPOSE: To reduce greatly the number of the I/O instructions given from the CPU as well as the data transfer frequency, by applying an interruption to the CPU after storing the data into the fixed position on the main memory when the data adequate to the inquiry items of the main memory is found out.
CONSTITUTION: The CPU not shown in the figure sets the fixed data to the device state register 2 and the file address register 4, and then sets the instruction code to the instruction register 5. Thus the intelligent device iNDV reads out the inquiry items of the main memory to start the retrieving action. And when the data adequate to the inquiry items is found out, the data, the byte number and the recording address of the data on the disk 12 are stored in the fixed position on the main memory. And then an interruption is applied to the CPU. Thus the CPU performs the process such as the display or the like to the stored data to carry out the subsequent retrieving instruction. As a result, a great reduction is possible to the I/O instructions given from the CPU as well as the data transfer frequency.
