摘要： Systems and methods of retraining a receiver provide for determining a minimum transition density for a derived clock data link to the receiver. A retraining flit is generated based on the minimum transition density. In one approach, the retraining flit is generated by defining control data and payload data for the retraining flit. Error detection data is determined for the retraining flit based on the control and the payload data. The control data, the payload data and the error detection data have sufficient transitions to meet the minimum transition density.

摘要： The current method and apparatus provides a novel approach to manage the power consumption of a high speed I/O interface by selectively turning off non-essential portions of the interface. Here only part of the interface is powered off as compared to the whole interface being turned off. From the upper layers (protocol/system) perspective, the interface is always “on”. Thus, this mechanism reduces link power by selectively turning off portions of the link, yet allowing for fast wake up in an interface power management architecture.

摘要： Disclosed are embodiments of a method, apparatus and system for a low power state for a point-to-point link. During the low power state, the signal on both conductors of a differential transmit pair are driven to electrical idle. Analog activity detectors are enabled during the low power state and are disabled during normal power state. Exit from the low power state does not require a physical layer re-initialization sequence. Other embodiments are also described and claimed.

摘要： In general, in one aspect, the disclosure describes an apparatus having an averager to receive differential output voltages of a transmitter and generate an average transmitter output voltage. A comparator is to compare the average transmitter output voltage to a reference voltage and generate a difference therebetween. An integrator is to integrate the difference between the average transmitter output voltage and the reference voltage over time. The integrated difference is fed back to the transmitter to bias the transmitter.
