摘要： A power management method for use in a computer system having a processor, a power management module and a phase lock loop circuit (PLL) is provided. The power management module is coupled to a plurality of peripheral modules and the computer system and the processor are capable of being operated in a working state and power saving states. The method includes the following. When the computer system is operated in the working state and the processor is entered into a lowest power consumption state among the power saving states, states of the peripheral modules are detected to determine whether a specific condition has been matched. If the specific condition is matched, the processor is directed to a control state to control the PLL according to a control state configuration.

摘要： A stand-by mode management module applied in a computer system having a BIOS (basic input/output system), a graphic module and a display module is provided. The computer system is operated in a working state and at least one stand-by state. The module includes a timer and an interrupt generation unit. The timer starts a count period when detecting that the computer system is idle. The interrupt generation unit generates an interrupt request to the BIOS to request the computer system to prepare to enter to a specific state when the count period is reached. When the specific state is entered, the computer system enters the stand-by state, a PLL (phase lock loop) of the display module keeps turning on, and PLLs other than the PLL of the display module are turned off and the graphic module acquires a frame stored in a fixed area of a storing unit and displays the acquired frame on the display module.

摘要： The present invention is directed to a stream context cache system, which primarily includes a cache and a mapping table. The cache stores plural stream contexts, and the mapping table stores associated stream context addresses in a system memory. Consequently, a host may, according to the content of the mapping table, directly retrieve the stream context that is pre-fetched and stored in the cache, rather than read the stream context from the system memory.

摘要： The present invention is directed to a transfer request block (TRB) cache system and method. A cache is used to store plural TRBs, and a mapping table is utilized to store corresponding TRB addresses in a system memory. A cache controller pre-fetches the TRBs and stores them in the cache according to the content of the mapping table.
