Abstract:
A multisystem network, a device and a method for accessing a data storage unit are arranged to allow processors in a plurality of devices to access the data storage unit. The data storage unit (80) has a data storage area divided in a first area for a first device (70) and a second area for a second device (60). The first and second devices are connected to the data storage unit (80) via a connection circuit (90). A first processor (701) in the first device (70) can access directly the data storage unit (80). The connection circuit (90) has provided therein an emulation register (907) corresponding to a register which stores a command or control data used for the first processor in the first device (70) to access the data storage unit (80). A second processor (601) in the second device (60) accesses the data storage unit (80) via the emulation register and with intervention of the first processor (701).
