A method and system of communicating data between a source interconnect device and a destination interconnect device are defined. The method includes adding an identification component to the data at the source interconnect device prior to communicating the data, and extracting the identification component at the destination interconnect device. The identification component is then processed at the destination interconnect device, the identification component relating to the contents of the data. The invention extends to a machine-readable medium embodying a set of instructions for executing the method and to an interconnect device.

Method and system to control the communication of data between a plurality of interconnect devices

In a master-slave configuration wherein a sleepmode activation is effected by the cessation of a clocking signal, the need for an analog device or auxiliary clock for detecting the cessation of the clocking signal is obviated by anticipating the cessation of the clock signal. Upon anticipating the cessation of the clock signal, the remaining clock signaling before cessation is used as required to effect a controlled power-down of the slave device. By eliminating the need for an analog clock cessation detector, the process tolerance constraints associated with analog circuitry can be avoided, the reliability and robustness of the design is improved, and the required testing is simplified, thereby reducing the cost of the device. In like manner, the elimination of an auxiliary clock generator reduces the cost and complexity of the device and system, and improves the device and system's overall reliability and testability. In accordance with this invention, the anticipation of the cessation of the clock signal is achieved by monitoring the communications among devices for commands that can be expected to affect the generation of the clock signal.
