Abstract

PURPOSE:To shorten the processing time by inputting picture data memorized in a disc device to a disc control device to make transferring of the picture from the disc control device to the display control device directly possible to display the data on a display device. CONSTITUTION:A picture data inputted from a disc device 1 to a disc control device 2 reduces the control signal to logic ''0'' in the data control circuit, and transferred to a display control device 4 through a connecting device 9. The data transmitted to the display control device 4 reduces the control signal to logic ''0'' in the data control circuit, and transfers to a display device 5. As above mentioned, the performance of a calculator is improved by enabling the access of a center processor 6 to a main memory device 3 even while transferring the image data to the display device 5 from the disc device 1. In addition, if other I/O device 10 is installed, access to the I/O device is also enabled. As the image data is transferred without passing through the main memory device 3, required time from display request to display is shortened.
