Information processing devices and methods

An information processing device comprising circuitry configured:

• to receive a first signal indicating a first change of information stored at a first address defined with respect to a first information processing entity and indicating a second change of information stored at a second address defined with respect to a second information processing entity, the second change of information depending on the first change of information and the second information processing entity being separate to the first information processing entity;
• to provide a second signal to the first information processing entity indicating the first change of information, the first information processing entity being configured to implement the first change of information stored at the first information processing entity in response to the second signal;
• and
• to provide a third signal to the second information processing entity indicating the second change of information, the second information processing entity being configured to implement the second change of information stored at the second information processing entity in response to the third signal.
