    摘要： A clock signal distribution system is disclosed for providing synchronous clock signals to a plurality of electronic circuit devices. The system includes a clock signal generator means for providing a single frequency sinusoidal clock signal output and a plurality of electronic circuit devices. A clock signal distribution network including interconnected resonant segments of a transmission line 13 connected to the clock signal of the clock signal generator and to the plurality of electronic circuit devices for providing separate synchronous, phase aligned clock signals to the electronic circuit devices. The transmission line segments have lengths matched to the clock signal frequency wavelengths to eliminate clock signal distribution problems such as skew, jitter and pulse distortions.

    摘要： Methods and apparatus are provided for choosing an energy-efficient coolant temperature for electronics by considering the temperature dependence of the electronics' power dissipation. This dependence is explicitly considered in selecting the coolant temperature T0 that is sent to the equipment. To minimize power consumption PTotal for the entire system, where PTotal=P0+PCool is the sum of the electronic equipment's power consumption P0 plus the cooling equipment's power consumption PCool, PTotal is obtained experimentally, by measuring P0 and PCool, as a function of three parameters: coolant temperature T0; weather-related temperature T3 that affects the performance of free-cooling equipment; and computational state C of the electronic equipment, which affects the temperature dependence of its power consumption. This experiment provides, for each possible combination of T3 and C, the value T0* of T0 that minimizes PTotal. During operation, for any combination of T3 and C that occurs, the corresponding optimal coolant temperature T0* is selected, and the cooling equipment is commanded to produce it.

    摘要： A method and system for reducing the computation complexity and improving accuracy of delay and crosstalk calculation in transmission-lines with frequency-dependent losses. An analysis tool based on restricted coupled-line topologies, simple two-dimensional to three-dimensional RLC matrix conversion, and use of prestored synthesized circuits that accurately capture frequency-dependent loss effects. The CAD tool can handle frequency-dependent resistive and inductive effects for coupled-interconnections on large microprocessor chips with >10K of critical nets. This is done in an interactive manner during the design cycle and allows first path fast product design.
