    • A frame-address matching function of a network controller is enhanced. In a full power-on mode, the controller performs conventional functions. In the low-power mode, the controller includes frame-address and frame-data matching, as well as pre-determined and programmable autonomous response to network protocol. If a match occurs with respect to the frame destination address or frame data, the system associated with the controller is placed in a wake-up state. If the controller is programmed to perform pattern matching inside the frame data area, upon such match in the frame data area the controller will generate and transmit on the network a simple response packet automatically. Conversely, if a match is not detected, no action is taken. The frame-data patterns are programmable with the capability to mask out certain data fields as desired which are protocol dependent and are substantially protocol dependent.
    • 增强了网络控制器的帧地址匹配功能。 在完全上电模式下,控制器执行常规功能。 在低功耗模式下,控制器包括帧地址和帧数据匹配,以及对网络协议的预定和可编程的自主响应。 如果相对于帧目的地地址或帧数据发生匹配,则与控制器相关联的系统被置于唤醒状态。 如果控制器被编程为在帧数据区域内执行模式匹配,则在帧数据区域中的这种匹配时,控制器将自动在网络上生成并发送简单的响应分组。 相反,如果未检测到匹配,则不采取任何操作。 帧数据模式可编程,具有根据需要屏蔽某些数据字段的能力,这些数据字段依赖于协议,并且基本上是协议相关的。
