The interconnect may include a pipe stage circuit coupled between a first processing circuit and a second processing circuit. This pipe stage circuit may include: a pipe stage component having a first input to receive a signal via the interconnect and a first output to output the signal; and a selection circuit having a first input to receive the signal from the first output of the pipe stage component and a second input to receive the signal via a bypass path, where the selection circuit is dynamically controllable to output the signal received from the first output of the pipe stage component or the signal received via the bypass path.

Abstract: Examples described herein relate to processor circuitry to issue a cache coherence message to a central processing unit (CPU) cluster by selection of a target cluster and issuance of the request to the target cluster, wherein the target cluster comprises the cluster or the target cluster is directly connected to the cluster. In some examples, the selected target cluster is associated with a minimum number of die boundary traversals. In some examples, the processor circuitry is to read an address range for the cluster to identify the target cluster using a single range check over memory regions including local and remote clusters. In some examples, issuance of the cache coherence message to a cluster is to cause the cache coherence message to traverse one or more die interconnections to reach the target cluster.

Abstract: A processor includes a cache-side address monitor unit corresponding to a first cache portion of a distributed cache that has a total number of cache-side address monitor storage locations less than a total number of logical processors of the processor. Each cache-side address monitor storage location is to store an address to be monitored. A core-side address monitor unit corresponds to a first core and has a same number of core-side address monitor storage locations as a number of logical processors of the first core. Each core-side address monitor storage location is to store an address, and a monitor state for a different corresponding logical processor of the first core. A cache-side address monitor storage overflow unit corresponds to the first cache portion, and is to enforce an address monitor storage overflow policy when no unused cache-side address monitor storage location is available to store an address to be monitored.
