Abstract: The disclosure relates to minimizing power consumption of a WiFi system-on-chip (SOC) during idle periods. The disclosed architecture includes memory banks for the WiFi SoC's embedded processor that can be independently powered on/off and a Memory Management Unit (MMU) to translate virtual addresses to physical addresses and generate exceptions to process accesses to virtual addresses without a corresponding physical address. The architecture can implement a demand paging scheme whereby a MMU fault from an access to code/data not within the embedded memory causes the processor to fetch the code/data from an off-chip secondary memory. To minimize page faults, the architecture stores WiFi client code/data within the embedded processor's memory that is repeatedly accessed with small periodicity or where there is an intolerance for delays of accessing the code/data.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (e.g., an access point or a station) capable of supporting multiple chain configuration modes may monitor traffic on a wireless channel. The wireless device may, based on the monitoring, determine a series of values for a metric that is indicative of communication conditions. The metric may be a packet rate, channel congestion, or signal strength. The wireless device may dynamically select one of the supported chain configuration modes in which to operate based on the series of values for the metric. In some cases, the wireless device may compute a value for the metric based on the series of values and compare the value of the metric to a predetermined threshold. In such cases, selection of the chain configuration mode may be based on the results of the comparison. In some examples, one or metrics may be used.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 能够支持多链配置模式的无线设备（例如，接入点或站）可以监视无线信道上的业务。 基于监控，无线设备可以确定指示通信条件的度量的一系列值。 度量可以是分组速率，信道拥塞或信号强度。 无线设备可以基于该度量的一系列值来动态地选择要在其中操作的所支持的链式配置模式之一。 在一些情况下，无线设备可以基于该一系列值计算该度量的值，并将该度量的值与预定阈值进行比较。 在这种情况下，链式配置模式的选择可以基于比较结果。 在一些示例中，可以使用一个或多个度量。
