摘要： Methods and apparatus for calibration of interface operation of a display device. In one exemplary embodiment of the invention, an embedded DisplayPort (eDP) source element (such as a graphics processing unit (GPU)) configures itself to support the minimum requirements necessary to support a sink element (such as a screen display). Unlike prior art solutions, minimum sink requirements are identified during a calibration process, and the source is configured accordingly. By tailoring the source to the specific requirements of the sink, the device can initialize faster, consume less power, etc. Moreover, in another aspect of the present invention, if a device does not initialize to an expected configuration based on prior calibration settings, the device can be flagged as having faulty or failing components.

摘要： Methods and apparatus for protecting data bus ports and their corresponding PHY devices from taking damage associated with excess voltage across one or more signal pairs during an intermittent connection. Such connections cause the signal pins to carry external device current which raises the signal voltage above the power rails, exceeding the PIN device ratings and causing PHY degradation or destruction. In an exemplary embodiment, an RC circuit is used to detect the voltage level across a signal pair. If this voltage level exceeds a certain preset voltage level, power to the outgoing serial bus port is shut off and return power is abated. While the circuit is responding, the exemplary embodiment uses a 3.6V Zener diode to bleed excess voltage to ground. A current monitor/limiter is also used for limiting current if the voltage level detected exceeds a certain threshold.

摘要： Methods and apparatus for the intelligent association of control symbols with special symbols that are transmitted over a network. In one embodiment, the association is utilized to improve DC-balance on a transmission medium. In an exemplary variant, the special symbols originate from line codes such as the 8B/10B line code, which format a digital signal so that is optimized for transmission over a given physical channel. These control symbols are divided up according to a first criterion, while the special symbols are further divided up according to a second criterion. The divided control symbols are then allocated to the divided special symbols using a pre-designated allocation algorithm, which may or may not include a scrambling algorithm. The allocation of the control symbols improves signal characteristics and electromagnetic interference (EMI) when various ones of control symbols are ultimately transmitted over a given transmission medium.

摘要： Systems and methods are disclosed for detecting the connection of a FireWire peer to a FireWire device. In one embodiment, a device may determine whether a peer connection is present based on peer detection circuit configured in each FireWire port of a FireWire device. When no peer is connected to a device, a peer connection in the circuit may be open, and a current path through the circuit may provide a low detect signal, indicating that no peer is connected. When a peer is connected to a detecting device, the current may pass through a resistance in the detected peer to provide a high detect signal, indicating that a peer is connected. In some embodiments, once a peer is detected, the FireWire system of the detecting device may be powered on, and the peer detection circuit may be powered off.
