ABSTRACT:
A memory accessing device is connected to a central processing unit and a memory unit via a common bus. The memory accessing device accesses the memory unit independently of the central processing unit. The device includes an address generating unit for generating an address, an address control unit for outputting the generated address to the bus, and a control unit for controlling the address control unit to suspend or terminate memory access controlled in an address pipeline mode when the memory accessing device internally or externally issues a request for the suspension or the termination of the memory access controlled in the address pipeline mode. The control unit terminates or suspends the memory access when it receives a request internally or externally of the memory accessing device for the suspension or the termination of the memory access.
