    • An apparatus of an aspect includes a plurality of cores. The plurality of cores are logically grouped into a plurality of clusters. A cluster sharing map-based coherence directory is coupled with the plurality of cores and is to track sharing of data among the plurality of cores. The cluster sharing map-based coherence directory includes a tag array to store corresponding pairs of addresses and cluster identifiers. Each of the addresses is to identify data. Each of the cluster identifiers is to identify one of the clusters. The cluster sharing map-based coherence directory also includes a cluster sharing map array to store cluster sharing maps. Each of the cluster sharing maps corresponds to one of the pairs of addresses and cluster identifiers. Each of the cluster sharing maps is to indicate intra-cluster sharing of data identified by the corresponding address within a cluster identified by the corresponding cluster identifier.

    • Layout-aware modular decoupled crossbar and router for on-chip interconnects and associated micro-architectures and methods of operation. A crossbar and router architecture called MoDe-X (Modular Decoupled Crossbar) is disclosed that supports 5-port routing for use in 2D mesh interconnects and is implemented through use of decoupled row and column sub-crossbar modules in combination with feeder wiring and control logic that enables routing between ports on the row and column sub-crossbar modules. The corresponding MoDe-X router supports 5-port routing between various router input and output port combinations while reducing both router area and power consumption when compared with a conventional 5×5 crossbar design and implementation. The MoDe-X micro-architecture can be configured to support both single and dual local port injection configurations.
    • 布局感知的模块化去耦交叉开关和路由器,用于片上互连和相关的微架构和操作方法。 公开了一种称为MoDe-X(模块化解耦交叉开关)的交叉开关和路由器架构,其支持用于2D网状互连的5端口路由,并且通过使用去耦的行和列子交叉模块与馈线布线和控制逻辑 这可以在行和列子交叉杆模块上的端口之间进行路由。 相应的MoDe-X路由器支持各种路由器输入和输出端口组合之间的5端口路由,与传统的5×5交叉开关设计和实现相比,可以减少路由器面积和功耗。 MoDe-X微架构可以配置为支持单端口和双端口注入配置。
