摘要： Embodiments of the invention provide an algorithm for dividing a link into one or more reduced-width links. For one embodiment of the invention, a multiplexing scheme is employed to effect a bit transmission order required by a particular cyclic redundancy check. The multiplexed output bits are then swizzled on-chip to reduce on-board routing congestion.

摘要： A technique is described by which two link agents with ports coupled together using a point-to-point interconnect in a system exchange their link width support capabilities and negotiate a link width that is mutually agreeable. The interconnect between each pair of agents comprises a pair of uni-directional links having multiple electrical wires, or lanes, where one link is used by a first agent to transmit data to a second agent and another link is used by the second agent to transmit data to the first agent.

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： A method for effecting an in-band reset of the physical layers of two agents interconnected through a link-based interconnection scheme. In accordance with one embodiment of the invention, a first of the two agents ceases its forwarded clock to initiate the in-band reset. Upon realization of the cessation, a second agent ceases its forwarded clock and proceeds to a reset state. The first agent then proceeds to a reset state. Subsequently, after waiting a specified period of time, both agents proceed with a re-initialization of the physical layer. In accordance with one embodiment of the invention, the re-initialization of the physical layer is effected without impacting other layers of the interconnection hierarchy.
