Abstract
PURPOSE: To omit the alteration or exchange for the hardware in case the buffer memory is added or deleted, by securing the same interface between the CPU and the buffer memory as well as between the buffer memory and the main memory each.
CONSTITUTION: Buffer memory 13 is provided independently between CPU11 and main memory 12. And the same constitution is secured for the interface between CPU11 and memory 13 as well as the interface between memory 13 and main memory 12. In such constitution, memory 13 is removed to secure the direct connection between CPU11 and memory 12, or the buffer memory is added. In such case, no alteration nor exchange is required for the interface hardware of CPU11 and memory 12.
