ABSTRACT:
There is provided a common-memory controlling apparatus which controls data transfer between a common-memory and a plurality of central processing units. A separating buffer separates a CPU bus connected to each of the central processing units from a common-memory bus connected to the common-memory. A request signal generating circuit generates a request signal for accessing to the common-memory when each of the central processing units requires accesses to the common-memory. An arbitration circuit arbitrates the request signals supplied by the central processing units so that a request signal corresponding to one of the central processing units is selected. The central processing unit having the highest priority level is served. A control signal generating unit generates control signals used for controlling a bus connection corresponding to the selected central processing unit so that the CPU bus connected to the selected central processing unit is connected to the common-memory.
