the device has two modules (10,20) each have a processor (11,21) and a local bus (12,22) serving peripherals (13,23) and memories (15,25). Each local bus (12,22) is connected to an inter-bus module (40) through a bidirectional buffer (30,50) controlled by automatic means (31,51). When one module (20) needs to access a peripheral of a second module (10) the automation (31) disconnects the processor (11) of the second module temporarily from it's local bus (12) and also connects together the two local bus (12,22) through bidirectional buffers (30,50) thus interchanging control of peripherals. |
