摘要： An USB composite device using hub link layer and UTMI interface is disclosed, which connects to a host through an USB cable. The device includes an USB physical layer, a hub link layer and plural functional link layers. The USB physical layer can receive and transmit USB signals. The hub link layer connects to the USB physical layer through an UTMI interface, has plural downlink ports to provide linking, and responds an USB transaction performed by the host. The plural functional link layers connect to the downlink ports of the hub link layer through plural UTMI interfaces.

摘要： A network notifying device applied to a first network device is provided, where the first network device is coupled to a second network device, and the network notifying device includes an interface control circuit, a clock generator and a counter. The interface control circuit is coupled to the second network device, and stores a notify command. The clock generator is utilized for generating a clock signal. The counter is coupled to the interface control circuit and the clock generator, and the counter counts the clock signal to periodically generate a trigger signal to the interface control circuit to trigger the interface control circuit to transmit the notify signal to the second network device. In addition, operations of the clock generator and the counter are independent from a processor of the first network device.

摘要： A state machine with a dynamic clock gating function according to the invention is disclosed. In the state machine, a gating clock control logic is used to gate a clock signal input to flip-flops which do not need a clock sample input. Accordingly, the total capacitance of capacitors which are charged/discharged following the state transition of a clock signal is greatly reduced, thereby decreasing the power consumption of the state machine.
摘要翻译：公开了具有根据本发明的动态时钟门控功能的状态机。在状态机中，门控时钟控制逻辑用于将输入到不需要时钟采样输入的触发器的时钟信号选通。因此，在时钟信号的状态转移之后被充电/放电的电容器的总电容大大降低，从而降低了状态机的功耗。
