    摘要: A system and method is disclosed for controlling signal conditioning parameters and a sampling parameter controlling conversion of a received signal to digital sampled values prior to decoding. The sampled values are decoded according to a comparison with expected values calculated according to a model of a transmission channel. The model is also updated from time to time by comparing the expected values with actual sampled values. Variation of the expected values over time is calculated. One or more of the signal conditioning parameters and the sampling parameter are adjusted according to a numerical minimization method such that the system BER is reduced.

    摘要: A multi-chip module (MCM) is described in which at least two substrates are mechanically coupled by an adhesive layer that maintains alignment and a zero (or near zero) spacing between proximity connectors on surfaces of the substrates, thereby facilitating high signal quality during proximity communication between the substrates. In order to provide sufficient shear strength, the adhesive layer has a thickness that is larger than the spacing. This may be accomplished using one or more positive and/or negative features on the substrates. For example, the adhesive may be bonded to: one of the surfaces and an inner surface of a channel that is recessed below the other surface; inner surfaces of channels that are recessed below both of the surfaces; or both of the surfaces. In this last case, the zero (or near zero) spacing may be achieved by disposing proximity connectors on a mesa that protrudes above at least one of the substrate surfaces.

    摘要: The disclosed embodiments provide a synchronizer latch circuit that facilitates resolving metastability issues. This synchronizer latch circuit includes a set of lightly loaded, cross-coupled transistors that form a metastable resolving and state-holding element that is coupled to two outputs. An incoming synchronization signal creates a voltage difference between the two outputs, but does not directly force a state change for the outputs. Instead, the data and clock inputs control transistors that allow neighboring power sources and/or ground network connections to weakly influence the outputs. The cross-coupled transistors then amplify the resulting voltage difference to generate valid output voltages, even when the data input and clock signal are received at roughly the same time. Thus, the synchronizer latch circuit facilitates rapidly resolving metastability and improving synchronizer performance.

    摘要: One embodiment of the present invention provides a system that facilitates capacitive communication between integrated circuit chips. The system includes a substrate having an active face upon which active circuitry and signal pads reside, and a back face opposite the active face. The system additionally includes an integrated circuit chip having an active face upon which active circuitry and signal pads reside, and a back face opposite the active face. Additionally, the integrated circuit chip is pressed against the substrate such that the active face of the integrated circuit chip is parallel to and adjacent to the active face of the substrate, and capacitive signal pads on the active face of the integrated circuit chip overlap signal pads on the active face of the substrate. The arrangement of the substrate and integrated circuit chip facilitates communication between the integrated circuit chip and the substrate through capacitive coupling via the overlapping signal pads.

    摘要: A method for calibrating an offset voltage of an amplifier used to amplify capacitively coupled communication signals is described. During this process, a common voltage is applied to one or more inputs to the amplifier. Next, an output of the amplifier is iteratively, measured, and charge is applied to the one or more inputs until the offset voltage is less than a pre-determined value. Note that applying the charge may involve applying a sequence of one or more charge pulses.

    摘要: One embodiment of the present invention provides a system that reduces power consumption by using capacitive coupling to perform a majority detection operation. The system starts by driving a plurality of signals onto a plurality of driven wires. The signals are then fed from each driven wire through a corresponding coupling capacitor to a single majority detection wire. Next, the system feeds signal on the majority detection wire and a bias voltage to a differential receiver. The output of the differential receiver switches if the signal on the majority-detection wire switches relative to the bias voltage. The system then uses the output of the differential receiver to optimize the signals from the plurality of driven wires for transmission across a long signal route. Optimizing the transmission of signals reduces the power consumed by the computer system.
