Abstract
PURPOSE: To increase the number of degrees of freedom of the array configuration of the extension data channel without executing the operation exceeding the upper limit of the memory access time, by easily dividing the extension data channel, and accomodating the side related to the memory operation in the original central processor equipment.
CONSTITUTION: The extension data channel is divided into the memory access control circuit 7-1 and the extension data channel device 7-2 except the memory access control circuit 7-1. This control circuit 7-1 is provided in the central processor equipment 1, and it is connected through the bus 2 to the memory 3 and other data channel devices 4-1, 4-2.... Also, the extension data channel device 7-2 is connected to the control circuit 7-1 by the interface 5 for extension. And, the number of degrees of freedom of the array configuration of the extension data channel is increased without executing the operation exceeding the upper limit of the memory access time.
