Abstract: A first plurality of integrated circuit blocks of a first chip are connected to a second plurality of integrated circuit blocks of a second chip. A cluster remapping table is provided on the second chip and is to be programmed to identify a desired asymmetric topology of the connections between the first plurality of integrated circuit blocks and the second plurality of integrated circuit blocks. Logic is to discover the actual topology of the connections between the first plurality of integrated circuit blocks and the second plurality of integrated circuit blocks and determine whether the actual topology matches the desired topology as described in the cluster remapping table.

Abstract: In an example, a shared uncore memory fabric of a system-on-a-chip (SoC) is configured to provide real-time power management. The SoC may include a power management agent to inform the shared fabric that the processing cores and peripherals will be idle for a time, and to negotiate a power-saving state. The uncore fabric may also include a local power manager that detects when no access requests have been received for a time, such as when cores are operating from cache. The shared fabric may then unilaterally enter a power-saving state, and remain in that state until an access request is received. In the power-saving state, power and/or clocks are gated, and the fabric's state is stored in retention cells. When a new access request is received, an ungated controller may handle preliminary processing while the local power manager restores the state and powers up the shared fabric.

Abstract translation: 在一个示例中，系统级芯片（SoC）的共享非存储存储器结构被配置为提供实时功率管理。 SoC可以包括电源管理代理，以通知共享结构处理核心和外围设备将空闲一段时间，并协商省电状态。 不合格结构还可以包括本地电力管理器，其检测何时没有接收到访问请求一段时间，例如当核心从高速缓存操作时。 共享结构可以单方面进入省电状态，并保持在该状态，直到接收到访问请求为止。 在省电状态下，电源和/或时钟门控，织物的状态存储在保留单元中。 当接收到新的访问请求时，非门控制器可以处理初步处理，而本地电源管理器恢复状态并使共享结构上电。
