摘要： According to the preferred embodiment, a device and method for reducing power consumption by reducing unneeded node toggling is provided. The preferred embodiment reduces unneeded node toggling in a circuit by utilizing either a pull-up or pull-down transistor to pull the input of the circuit to a state that minimizes power consumption during periods in which the circuit is inactive. By tying the circuit input high or low during inactivity, node toggling is reduced or eliminated in that circuit. In the preferred embodiment, the inputs to the circuit all pulled after a time of inactivity which is proportional to the leakage current of the leakiest transistor in the circuit. By timing the input pulling proportional to the leakage current, the power consumption is minimized without excessive power loss caused by the pulling itself.

摘要： A differential sinusoidal signal pair is generated on an integrated circuit (IC). The differential sinusoidal signal pair is distributed to clock receiver circuits, which may be differential amplifiers. The clock receiver circuits receive the differential sinusoidal signal pair and convert the differential sinusoidal pair to local clock signals. Power consumption and noise generation are reduced as compared to conventional clock signal distribution arrangements.

摘要： A system and method for interconnecting a plurality of cores into a single functional core. The method involves creating for each core a pin configuration structure based on a set of configuration rules. When the cores to be interconnected are selected, the pin configuration structure is accessed by the configurator program tool of the present invention. The configurator program tool then connects the cores together using the pin configuration structure and configuration rules for the selected cores. The configurator program tool generates an error-free high level model of the interconnected cores. The configurator program tool allows configuration flexibility and is general enough to handle most configuration scenarios. The tool is also easy to code, extensible, and can be applied to existing core designs with no modification of the cores themselves.

摘要： A system and method for providing on-chip voltage distribution and regulation. In accordance with the system of the present invention, an IC chip includes a source voltage plane having a source supply rail for supplying power to the IC chip and a source ground rail for sinking power supplied therefrom. At least one intermediate ground rail is connected between the source supply rail and the source ground rail to divide the source voltage plane into multiple intermediate voltage planes. The intermediate ground rail serves as a supply rail for a subsequent intermediate voltage plane such that the intermediate voltage planes are series-connected.

摘要： An integrated circuit includes a CPU, a power management unit and plural functional units each dedicated to executing different functions. The power management unit controls the threshold voltage of the different functional units to optimize power/performance operation of the circuit and intelligent power management control responds to the instruction stream and decodes each instruction in turn. This information identifies which of the functional units are required for the particular instruction and by comparing that information to power status, the intelligent power control determines whether the functional units required to execute the command are at the optimum power level. If they are, the command is allowed to proceed, otherwise the intelligent power control either stalls the instruction sequence or modifies process speed.
