摘要:
A method for managing power consumptions of a sending driver and a receiving driver within a data communication system is disclosed. The sending driver is coupled to a sender and a sensor. The receiving driver is coupled to a receiver and a controller. The sensor adjusts a transmission frequency and a supply voltage level to the sending driver according to the amount of data that needed to be sent by the sender. Data within the sender are then transmitted by the sending driver to the receiving driver according to the adjusted transmission frequency and the adjusted supply voltage level.
摘要:
An integrated circuit and a design structure are disclosed. An integrated circuit may comprise: multiple clocked elements; a clock signal source providing clock signals to the multiple clocked elements; and a clock shifting means coupled between the clock signal source and each of the multiple clocked elements; wherein the clock shifting means shifts clock signals of the multiple clocked elements such that the clock signals of the multiple clocked elements have aligned active edges and misaligned inactive edges to reduce the clock noise generated by the inactive edges of the clock signals.
摘要:
A method and system for reducing clock noises are disclosed. A clock signal includes active edges and inactive edges. Inactive edges produce clock noise but are not critical to the functionality of the clock signal. That is, only active edges are critical to proper timing of an integrated circuit (IC). As such, inactive edges of clock signals to clocked elements of an IC may be shifted to be misaligned to one another. As a consequence, peak noise produced by the inactive edges will be spread over a large area and therefore will be reduced in amplitude.
