摘要： A computer subsystem of a computer includes a CPU, RAM, display, storage device, input device(s), and a digital-audio generating IC. A CD-ROM subsystem of the computer includes a CD-ROM drive and CD-ROM control buttons for controlling CD-ROM drivers operation while playing audio CDs. An audio-interface IC of the CD-ROM subsystem couples a bus of the computer subsystem to the CD-ROM drive, and to the control buttons. The audio-interface IC, in one operating mode, relays commands and data between the bus and the CD-ROM drive. A second operating mode permits turning the computer subsystem off while the audio-interface IC autonomously responds to the control buttons and transmits commands to the CD-ROM drive for playing an audio CD.

摘要： A power management PC expansion card controller that includes power on reset circuitry to reset power management enable registers during a reset period, thereby ensuring that the PME registers correctly identify the power management capabilities of the controller. Once the PME registers are reset, an instruction may be provided to change the state of the registers from a default reset state to a state that supports advanced power management capabilities, for example wake-up functions. Additionally, the controller includes blocking circuitry to block conventional reset signals from resetting the power management and proprietary registers if the PME register is instructed to change states, thereby preserving the data contained in the power management and proprietary registers against future reset events. The controller of the present invention supports advanced power management specifications without requiring additional pinout arrangement or reassignment of pin functionality, so that the controller of the present invention can be implemented in current computer system without a the need for retooling or re-layout of system board circuitry and wiring diagrams.
摘要翻译：电源管理PC扩展卡控制器，包括上电复位电路以复位电源管理在复位期间启用寄存器，从而确保PME寄存器正确识别控制器的电源管理功能。一旦PME寄存器被复位，可以提供指令来将寄存器的状态从默认复位状态改变为支持高级电源管理能力的状态，例如唤醒功能。此外，如果指示PME寄存器改变状态，则控制器包括阻塞常规复位信号的复位信号，以复位电源管理和专有寄存器，由此保留电源管理和专有寄存器中包含的数据以防止未来复位事件。本发明的控制器支持高级电源管理规范，而不需要额外的引脚排列或引脚功能的重新分配，使得本发明的控制器可以在当前的计算机系统中实现，而不需要对系统板进行改装或重新布局电路和接线图。

摘要： A controller for use with laptop and notebook digital computers for reproducing compressed digital audio and video files. The controller includes a drive interface for traversing and accessing data stored on a drive of a computer system. Function keys or a remote controller permit users to access drives containing desired data. The selected data is read from the drive. A decoder circuit parses the data into audio data and video data and decodes each set of data to generate a decoded audio data stream or video data stream. The audio data stream can be converted to an analog signal by the controller, or sent to an external ADC of the computer system. Advantageously, the controller operates when the computer system is in an inactive state, for example in power saving mode or OFF, and operates in passthrough or bypass mode when the computer system is ON or active.
