Abstract

PURPOSE: To extract a needed data part by transferring data required by a computer from a main memory to a buffer memory on a unit of certain width including data and by properly using both reference pulses of the computer and memory.
CONSTITUTION: The external memory used as a picture terminal equipment connected to the computer is constituted by combining a high-speed and small-capacity buffer memory and a low-speed and large-capacity main memroy. The computer performs addressing to transfer data of the unit width composed of several pieces of data from the main memory. While a data transfer pulse is effective so as to extract assigned data from unit-width data, the address of the memory is advanced by a strobed pulse and while not, on the other hand, the address is advanced by the reference pulse in the exterbal memory, thereby extracting discontinuous data continuously.
