摘要： One embodiment of the present invention provides a system that facilitates reducing the power needed for proximity communication. This system includes an integrated circuit with an array of transmission pads that transmit signals using proximity communication. This array is comprised of a set of macropads, where each given macropad is comprised of a set of micropads that can be configured to transmit a signal. A steering fabric routes signals to and within macropads, such that a subset of the micropads in the array can be configured to transmit the signal to a receiving component. Each macropad receives a limited number of input signals, with the steering fabric routing input signals to the micropads of the macropads. By limiting the number of input signals that are routed to the micropads of the macropads, the steering fabric eliminates redundant steering configurations for the array and reduces the power needed to transmit the signal.

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 facilitates detecting and correcting errors. The system operates by receiving a data packet comprised of p words on a communication pathway, wherein each bit of a word is received on a separate data line in a set of data lines that comprise the communication pathway. The system also receives a time signature t on the communication pathway, wherein t contains per-bit error information for the p words in the data packet. As the data packet is received, the system performs an error-detection operation on each data bit of the data packet in parallel, wherein the error-detection operation generates per-bit error information for each bit position across the p words in the data packet. Finally, the system compares the generated per-bit error-information with the corresponding per-bit error information in the time signature t to determine if there exists an error.

摘要： One embodiment of the present invention provides a capacitively-coupled receiver amplifier that has an input with no DC coupling. A DC voltage is programmed on the input. During programming, a transmitter is held at a voltage at a midpoint between a voltage that represents a logical “1” and a voltage that represents a logical “0” and the input voltage of the receiver amplifier is programmed to be substantially the switching-threshold voltage for the receiver amplifier. Then, during normal data communication, the transmitter drives high and low electrical signals that are coupled to the receiver amplifier. Since the input of the receiver amplifier has been substantially set to the DC voltage, the receiver amplifier need not control the DC voltage of the input for each transition in the electrical signals.

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.

摘要： In a proximity communication system, transmit elements on one chip are aligned with receive elements on a second chip juxtaposed with the first chip. However, if the elements are misaligned, either statically or dynamically, the coupling between chips is degraded. The misalignment may be compensated by controllably degrading performance of the system. For example, the transmit signal strength may be increased. The bit period or the time period for biasing each bit may be increased, thereby decreasing the bandwidth. Multiple coupling elements, such as capacitors, may be ganged together, thereby decreasing the number of channels. The granularity of symbols, such as images, may be increased by decreasing the number of bits per symbol.
