Abstract:
A shared memory controller is to service load and store operations received, over data links, from a plurality of independent nodes to provide access to a shared memory resource. Each of the plurality of independent nodes is to be permitted to access a respective portion of the shared memory resource. Interconnect protocol data and memory access protocol data are sent on the data links and transitions between the interconnect protocol data and memory access protocol data can be defined and identified.
Abstract:
Physical layer logic is provided that is to receive data on one or more data lanes of a physical link, receive a valid signal on another of the lanes of the physical link identifying that valid data is to follow assertion of the valid signal on the one or more data lanes, and receive a stream signal on another of the lanes of the physical link identifying a type of the data on the one or more data lanes.
Abstract:
A coherence protocol message is sent corresponding to a particular cache line. A potential conflict involving the particular cache line is identified and a forward request is sent to a home agent to identify the potential conflict. A forward response can be received in response to the forward request from the home agent and a response to the conflict can be determined
Abstract:
Methods and apparatus relating to provide bimodal functionality between a coherent link and memory expansion are described. In one embodiment, a processor is coupled to one or more agents via a coherent interconnect. The processor is also coupled to one or more Dual Inline Memory Modules (DIMMs) via a link logic. The logic supports read or write commands directed at the one or more DIMMs based on a single bit of data. Other embodiments are also disclosed and claimed.
