    Abstract: Techniques for power gating. A first on-die router has an output port to receive data from a switching fabric. The output port is placed in a power-gated state if there is no activity in the output port for a current cycle and no messages are to be received by the output port during a subsequent cycle. A second on-die router has an input port coupled with the output port of the first on-die router. The input port is placed in a power-gated state if an input port buffer is empty and the output port is not active. Power-gating of the input port and the output port are independent of each other.

    Abstract: Disclosed embodiments relate to a cache line eviction algorithm. In one example, a system includes a last level cache (LLC) having multiple ways, each allocated to one of multiple priorities, each having specified minimum and maximum ways to occupy, a cache control circuit (CCC) to store an incoming cache line (CL) having a requestor priority to an invalid CL, if any, otherwise, when the requestor priority is a lowest priority and has an occupancy of one or more, or when the occupancy is at a maximum, to evict a least recently used (LRU) CL of the requestor priority, otherwise, when the occupancy is between a minimum and a maximum, to evict a LRU CL of the requestor or a lower priority, otherwise, when the occupancy is less than the minimum, to evict a LRU CL, if any, of the lower priority, and otherwise, to evict a LRU CL of a higher priority.

    Abstract: Techniques and mechanisms for interconnecting network circuitry of an integrated circuit (IC) die and physical layer (PHY) circuits of the same IC die. In an embodiment, nodes of the network circuitry include first routers and processor cores, where the first routers are coupled to one another in an array configuration which includes rows and columns. First interconnects each extend to couple both to a corresponding one of the PHY circuits and to a corresponding one of the first routers. For each of one or more of the first interconnects, a respective one or more rows (or one or more columns) of the array configuration extend between the corresponding PHY and the corresponding router. In another embodiment, the network circuitry comprises network clusters which each include a different respective row of the array configuration.
