摘要： An optical device that can be used in a range of telecommunications applications including optical multiplexers/demultiplexers and optical routers. The optical device includes an optical processing loop which allows multi-stage performance characteristics to be achieved with a single physical filtration stage. Optical processing on the first leg and second legs of the loop is asymmetrical thereby improving the integrity of the optical signals by effecting complementary chromatic dispersion on the first and second legs. In an embodiment of the invention the optical device includes a fundamental filter cell, a retro reflector and a splitter/combiner. The fundamental filter cell filters optical signals propagating on each of two legs of an optical loop which intersects the fundamental filter cell. The fundamental filter cell operates as a full waveplate to the odd set of channels and a half waveplate to the even set of channels on a selected one of the two legs and as a half waveplate to the odd set of channels and a full waveplate to the even set of channels on a remaining one of the two legs. The retro reflector optically couples with the fundamental filter cell to reflect the optical signals from one of the two legs to an other of the two legs to form the optical loop. The splitter/combiner optically couples between the fundamental filter cell and the retro reflector to split or combine the odd set of channels and the even set of channels depending on the propagation direction of the optical signals along the optical loop.

摘要： A method of reducing power consumption in a computing platform is disclosed. An endpoint-device that is coupled to the computing platform includes a first data buffer and a second data buffer. The first data buffer buffers outgoing data to be transmitted to an external device via a first communications medium. The second data buffer buffers incoming data received from the external device via the first communications medium. At least one of the first or second data buffers may selectively communicate with the computing platform, via a second communications medium, during an active window of the other data buffer. The active window may be requested by the first and/or second data buffers based, at least in part, on a system idle signal. For some embodiments, the first communications medium is an Ethernet link. Further, for some embodiments, the second communications medium is a Peripheral Component Interconnect Express (PCIe) link.

摘要： Techniques are disclosed that allow for power conservation in integrated circuit memories, such as SRAM. The techniques can be embodied in circuitry that allows for floating of bitlines to eliminate or otherwise reduce power leakage associated with precharging bitlines. For instance, the techniques can be embodied in a bitline floating circuit having a single logic gate for qualifying the precharge control signal with a wake signal, so that precharging of the bitline does not occur if the wake signal is not in an active state. The techniques further allow for the elimination or reduction of unnecessary power consumption by the I/O circuitry or the memory array, such as when the memory array is not being accessed or when the array or a portion thereof is permanently disabled for yield recovery.
