    Abstract: A high speed serial interface is provided. In one aspect, the high speed serial interface uses three phase modulation for jointly encoding data and clock information. Accordingly, the need for de-skewing circuitry at the receiving end of the interface is eliminated, resulting in reduced link start-up time and improved link efficiency and power consumption. In one embodiment, the high speed serial interface uses fewer signal conductors than conventional systems having separate conductors for data and clock information. In another embodiment, the serial interface allows for data to be transmitted at any speed without the receiving end having prior knowledge of the transmission data rate. In another aspect, the high speed serial interface uses polarity encoded three phase modulation for jointly encoding data and clock information. This further increases the link capacity of the serial interface by allowing for more than one bit to be transmitted in any single baud interval.

    Abstract: Aspects of adjusting application parameters for interference mitigation are disclosed. In one aspect, a computing device is provided that employs a control system configured to detect and mitigate electromagnetic interference (EMI) generated within the computing device. More specifically, the control system is configured to detect possible EMI conditions and adjust parameters within the computing device to mitigate such EMI. In this manner, the computing device includes an aggressor application and a victim receiver. The control system is configured to analyze performance tradeoffs based on an acceptable performance level of the aggressor application and the performance degradation experienced by the victim receiver. Based on such analysis, the control system is configured to adjust parameters associated with the aggressor application to mitigate the EMI. Thus, the control system provides designers with an additional tool that may reduce the performance degradation of the victim receiver attributable to the EMI.

    Abstract: In a multi-wire channel that includes at least three wires, each unique wire pair of the multi-wire channel has approximately the same signal propagation time. In this way, jitter can be mitigated in the multi-wire channel for signaling where, for a given data transfer, a differential signal is transmitting on a particular pair of the wires and every other wire is floating. In some implementations, matching of the signal propagation times involves providing additional delay for at least one of the wires. The additional delay is provided using passive signal delay techniques and/or active signal delay techniques.

    Abstract: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. Information is transmitted in N-phase polarity encoded symbols. A clock recovery circuit may be calibrated based on state transitions in a preamble transmitted on two or more connectors. A calibration method is described. The method includes detecting a plurality of transitions in a preamble of a multiphase signal and calibrating a delay element to provide a delay that matches a clocking period of the multiphase signal. Each transition may be detected by only one of a plurality of detectors. The delay element may be calibrated based on time intervals between detections of successive ones of the plurality of transitions.

    Abstract: Systems and methods for multi-phase signaling are described herein. In one embodiment, a method for receiving data comprises receiving a sequence of symbols from a plurality of conductors, and generating a clock signal by detecting transitions in the received sequence of symbols. The method also comprises delaying the received sequence of symbols, and capturing one or more symbols in the delayed sequence of symbols using the clock signal, wherein a previous symbol in the delayed sequence of symbols is captured using a clock pulse in the clock signal generated based on a detected transition to a current symbol in the received sequence of symbols.

    Abstract: To accommodate multiple masters over bus architectures supporting a single master device, a mechanism is provided for an inactive master device to trigger an IRQ signal over a shared, single line IRQ bus. A current master then polls the other inactive master devices over a shared data bus to ascertain which inactive master device is asserting the IRQ signal. Upon identifying the asserting inactive master device, the current master device grants control of the data bus to the new master device, thereby making the inactive master the new active master device.

    Abstract: A master device is provided which is coupled to a shared single line interrupt request (IRQ) bus and a control data bus. The master device group slave devices coupled to the shared single line IRQ bus into one or more groups, where each group is associated with a different IRQ signal. The master device then monitors the IRQ bus to ascertain when an IRQ signal is asserted by at least one slave device. The master device then identifies a group to with which the IRQ signal is associated. The slave devices for the identified group are then scanned or queried by the master device to ascertain which slave device asserted the IRQ signal on the IRQ bus. Each group uses a distinguishable IRQ signal to allow the master device to ascertain which group to query or scan.

    Abstract: System, methods and apparatus are described that offer improved performance of a serial bus used for Inter-Integrated Circuit (I2C) and/or camera control interface (CCI) operations. CCI extension (CCIe) devices are described. CCIe devices may be configured as a bus master or as a slave. In one method, a CCIe transmitter may generate a transition number from a set of bits, convert the transition number into a sequence of symbols, and transmit the sequence of symbols in the signaling state of a two-wire serial bus. Timing information may be encoded in the transitions between symbols of consecutive pairs of symbols in the sequence of symbols. For example, each transition may cause a change in the signaling state of at least one wire of the two-wire serial bus. A CCIe receiver may derive a receive clock from the transitions in order to receive and decode the sequence of symbols.
