摘要： A low-power digital audio decoding and playing system and method for computing devices provides a low-cost, low power-consumption, long-battery-life audio playing and decoding system, which may be used to play compressed audio files of various formats. In one aspect, a computer system adapted to play audio files comprises a system CPU (6), memory (4), at least one drive comprising compressed audio data (2), and an audio controller coupled to the system CPU (6), memory (4) and drive (2). The audio controller is adapted to cause the drive (2) to read the compressed audio data from the drive (2), to cause the system CPU (6) to decompress the compressed audio data from the drive (2) into decompressed audio data, to cause the decompressed audio to be stored in the memory (4), and to cause the decompressed audio data to be retrieved from the memory (4) for playing.

摘要： A low-power audio CD player for portable computers permits operation of the CD-ROM subsystem (106) when power is not being supplied to the computer subsystem (104). The audio interface (102) is adapted to generate signals to operate the audio device and play the audio CD when power is not being supplied to the computer subsystem or to the CPU. A method for playing an audio CD in a computer system comprises deenergizing a computer CPU; and controlling, using an audio interface coupled to a digital computer bus in parallel to a digital computer bus controller and an audio device capable of playing an audio CD, the audio device and a computer audio amplifier to play an audio CD without supplying energy to the CPU.

摘要： A computer system includes a system CPU responsive to a control signal to load a first operating system or a second operating system. The first operating system is run by the computer system in a first operation mode and the second operating system is run by the computer system in a second entertainment mode. A PC operating in an entertainment mode may operate a variety of entertainment software applications. A quick boot process is also provided. The quick boot process may include an accelerated BIOS boot process that defers and delays appropriate tasks. The quick boot process may also include: detecting a condition; performing a BIOS boot process; loading an image file associated with the condition; and executing the image file associated with the condition. The condition may be that associated hardware is unchanged from a previous boot. A parental control system is also disclosed.

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.
