Abstract: In one example, a semiconductor die includes a plurality of agents and a fabric coupled to at least some of the plurality of agents. The fabric may include at least one router to provide communication between two or more of the plurality of agents, the at least one router coupled to a first agent of the plurality of agents, where the first agent is to send a first message to the at least one router, the first message comprising a first header including a first source identifier, and the at least one router is to validate that the first source identifier is associated with the first agent and if so to direct the first message towards a destination agent, and otherwise to prevent the first message from being directed towards the destination agent. Other embodiments are described and claimed.

Abstract: A multi-level memory architecture scheme to dynamically balance a number of parameters such as power, thermals, cost, latency and performance for memory levels that are progressively further away from the processor in the platform based on how applications are using memory levels that are further away from processor cores. In some examples, the decision making for the state of the far memory (FM) is decentralized. For example, a processor power management unit (p-unit), near memory controller (NMC), and/or far memory host controller (FMHC) makes decisions about the power and/or performance state of the FM at their respective levels. These decisions are coordinated to provide the most optimum power and/or performance state of the FM for a given time. The power and/or performance state of the memories adaptively change to changing workloads and other parameters even when the processor(s) is in a particular power state.
