摘要:
In one embodiment, the present invention includes a method for receiving a first portion of a first packet at a first agent and determining whether the first portion is an interleaved portion based on a value of an interleave indicator. The interleave indicator may be sent as part of the first portion. In such manner, interleaved packets may be sent within transmission of another packet, such as a lengthy data packet, providing improved processing capabilities. Other embodiments are described and claimed.

In one embodiment of the present invention, a method may include separating incoming transactions to an agent of a coherent system into at least a first channel, a second channel, and a third channel, based upon a type of the incoming transactions. The incoming transactions may be sent by a peer device coupled to the coherent system. By separating the transactions based on type, deadlocks may be avoided.

A predetermined network packet is utilized for power reduction in either or both of a transmitter and receiver when information is not needed. Upon detection of the predetermined network packet type, various portions of the transmitter and/or receiver may be clock gated or powered down.

Systems and methods of processing write transactions provide for combining write transactions on an input/output (I/O) hub according to a protocol between the I/O hub and a processor. Data associated with the write transactions can be flushed to an I/O device without the need for proprietary software and specialized registers within the I/O device.

In a cache coherency protocol multiple conflict phases may be utilized to resolve a data request conflict condition. The multiple conflict phases may avoid buffering or stalling conflict resolution, which may reduce system inefficiencies.

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.
