    摘要: Embodiments of the invention are directed to a single driver that can be used to transmit data with configurable levels of pre-emphasis, and can have either a constant or adjustable driver output impendence, selectively. One embodiment, directed to a driver apparatus, is associated with a digital communication channel for transmitting data signals, wherein at least one of the signals includes a higher frequency component. The apparatus comprises a first sub-driver that has a constant output impedance, and is selectively configurable to implement two or more different levels of pre-emphasis. The apparatus further comprises one or more second sub-drivers. A set of connector elements are provided for connecting the first sub-driver and each of the second sub-drivers in parallel relationship with one another, so that the first sub-driver and each of the second sub-drivers all have inputs that respectively receive a specified driver apparatus input signal, and all have outputs that are connected together to selectively provide a specified driver apparatus output impedance. The apparatus further includes a device that is connected to selectively disable and enable each of the second sub-drivers.

    摘要: A processing device, processing system, method, and design structure for an enhanced microprocessor interconnect with bit shadowing are provided. The processing device includes shadow selection logic to select a driver bit position as a shadowed driver value, and line drivers to transmit data for the selected driver bit position and the shadowed driver value on separate link segments of a bus. The processing device also includes shadow compare logic to compare a selected received value with a shadowed received value from the bus and identify a miscompare in response to a mismatch of the compare, and shadow counters to count a rate of the miscompare relative to a bus error rate over a period of time. A defective link segment is identified in response to the rate of the miscompare within a predefined threshold of the bus error rate.

    摘要: The slew rate of signals output from an integrated circuit is selectively controlled to optimize the quality of the output data signal depending upon whether the communication channels require a faster or slower slew rate. Faster slew rates may be utilized when the communication channels are prone to attenuation, while slower slew rates may be implemented in the communication channels when crosstalk is more of a concern.

    摘要: Signaling between two or more ICs use a signaling scheme wherein a reference signal is generated at the driver side and the receiver side. The driver side reference signal is coupled to the receiver side reference signal with a transmission line channel forming a reference channel. Data signal channels are paired with a reference channel between each two adjacent data channels. Adjacent pairs of data signal channels are each separated with an empty wiring channel. The paired data signals are received in one input of a differential receiver. The reference signal of the reference channel between the two paired data channels is coupled to the other input of the two differential receivers. Coupling from the paired data channels to the reference channel appears a common mode noise and is rejected by the differential receivers. The number of channels is reduced from a full differential signaling scheme.

    摘要: Circuitry used to de-skew data channels coupling parallel data signals over a communication link employs SOI circuitry that is subject to generating pulse distortion due to the history effect modifying threshold voltages. To substantially eliminate the pulse distortion, data signals are XOR with a repeating scramble data pattern that generates scrambled data with a minimum average ratio of logic ones to logic zeros logic zeros to logic ones. The scrambled data is sent over the communication link and de-skewed in the SOI circuitry with little or no pulse distortion. The scramble data pattern is again generated at the receiver side of the communication link after a delay time to synchronize the logic states of the scramble data pattern that generated the scrambled data with the scrambled data at the receiver side. The delayed scrambled data pattern is again XOR'ed with the scrambled data to recover the data signal.

    摘要: Individual stages of a multistage electronic receiver include a pair of conductive isolation regions around each stage to isolate each stage from the other stages and thereby prevent feedback and external noise problems. Each pair of isolation regions includes a P+ ring and an N+ ring adjacent to each other to shunt hole carriers and electron carriers, respectively. Removal of the carriers does not have to wait for recombination of the carriers. The region which has the same conductivity type as the substrate extends entirely through an epitaxial or diffused layer to the substrate to collect hole carriers in the substrate.

    摘要: A multi-use physical (PHY) architecture that includes a PHY connection that includes one or more bit lines and that is communicatively coupled to a first processor. The PHY connection is configurable to carry signals between the first processor and a second processor, or between the first processor and a memory. The one or more bit lines are configured to carry signals bi-directionally at a first voltage when the PHY connection is configured to carry signals between the first processor and the memory. The one or more bit lines are configured to carry signals uni-directionally at a second voltage when the PHY connection is configured to carry signals between the first processor and the second processor. The second voltage is different than the first voltage.
