A method for centralized link power management control (CLMC), performed by a north-bridge of a processing unit, comprises the following steps. A data transmission status of a bus is monitored. CLMC is activated to configure devices corresponding to the bus in order to speed up data transmission of the bus when detecting that the data transmission status of the bus is continually busy. CLMC is activated to configure devices corresponding to the bus in order to slow down data transmission of the bus when detecting that the data transmission status of the bus is continually idle.

Methods and systems for centralized link power management control (CLMC)

A power saving method is disclosed. A halt instruction is issued to enable transition from an operational state to a power saving state. The processor broadcasts a message to a chipset. The chipset receives the sleep message and enters a power saving state, and asserts a hardware pin to disable a data bus connecting the processor and the chipset. It is determined whether a request for data transaction required during the power saving process is issued to the chipset. If the request is issued to the chipset, the chipset deasserts the hardware pin to enable the data bus, transmits the request to the processor; and, when data transaction is complete, asserts the hardware pin by the chipset to disable the data bus.

Method and apparatus for asserting a hardware pin to disable a data bus connecting a processor and a chipset during power saving state

A method for centralized dynamic link configuration (CDLC), performed by a processor and a chipset is provided. In the method, the processor first notifies the chipset of CDLC enablement. The chipset then issues a command to the processor after receiving notification of CDLC enablement. The processor broadcasts a preparation completion signal after receiving the command. The chipset asserts a signal and activates a timer to start counting after receiving the preparation completion signal. The processor configures devices of the processor, corresponding to a bus, according to one of multiple sets of first link management mode (LMM) configuration parameters in a first LMM register of the processor, indicated by first link management action field (LMAF) code in a first LMAF register of the processor, after detecting that the signal is asserted. The chipset configures devices of the chipset, corresponding to the bus, according to one of multiple sets of second LMM configuration parameters in a second LMM register of the chipset, indicated by second LMAF code in a second LMAF register of the chipset, when asserting the signal. The chipset de-asserts the signal when the timer reaches a predetermined value.

A bridge device electrically connected to a first AGP bus, a second AGP bus, and a PCI bus is provided. The bridge device has a first bridge, a second bridge, and a controller. The first bridge is electrically connected between the first AGP bus and the second AGP bus. The second bridge is electrically connected between the first AGP bus and the PCI bus. The controller is electrically connected to the first AGP bus, the first bridge, and the second bridge. As a configuration cycle corresponding to the first bridge being transmitted through the first AGP bus to the controller, the controller responds a preset message implying that the first bridge does not exist.

Multi-port bridge device

An improved steamer (second application) has properties of small volume, no need of change water, fast speed of steam generation, save power, and essence therapy. The steamer includes a main body, a filter, a steam supply unit, and a control unit. Water input tube enters a steam generator of the main body through the filter. The steam generator is installed with an electric heater at the lower part. The heater is enclosed by mineral wool and has a temperature sensor and a water level detector. By controlling the water level in the steam generator and function of power safety cut, the generated steam is straddled out through the steam supply unit. Inside of the steam supply unit, it has two separated gas holes and a containing space. The essence is filled into the containing space, and can be evaporated together with the steam to be supplied from the gas holes.
