Abstract: In one embodiment, the present invention includes an apparatus having an adapter to communicate according to a personal computer (PC) protocol and a second protocol. A first interface coupled to the adapter is to perform address translation and ordering of transactions received from upstream of the adapter. The first interface is coupled in turn to heterogeneous resources, each of which includes an intellectual property (IP) core and a shim, where the shim is to implement a header of the PC protocol for the IP core to enable its incorporation into the apparatus without modification. Other embodiments are described and claimed.

Abstract: A transaction detection device is described having inputs to couple to communication lines. Each communication line to transport notification of a packet observed by a link probe within a computing system containing point-to-point links between nodes. Each of said nodes having at least one processing core. The transaction detection device also comprises logic circuitry to determine from said notifications whether a looked for transaction has occurred within said computing system.

Abstract: A method is described that involves within a link based computing system, opportunistically transmitting, into a network utilized by components of the link based computing system, one or more packets that contain computing system state information. The computing system state information includes software state information created through execution of software by said link based computing system. The method also involves collecting the computing system state information at a monitoring and/or debugging system attached to the link based computing system in order to analyze the link based computing system's operation.

Abstract: A scheme for exposing internal debug values in an in-band means via debug packets that are injected sequentially with normal link traffic on a link and do not interrupt or otherwise interfere with normal operation of the link or related devices. Therefore, this proposal does not require additional pins since the debug values are exposed via debug packets in an in-band means along with normal link traffic and the debug values are exposed synchronously with normal link traffic since the debug packets are injected sequentially.
