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.
摘要翻译：用于便携式计算机的低功率音频CD播放器允许当未向计算机子系统（104）供电时CD-ROM子系统（106）的操作。音频接口（102）适于产生用于操作音频设备的信号并且当未向计算机子系统或CPU供电时播放音频CD。一种用于在计算机系统中播放音频CD的方法包括断电计算机CPU; 以及使用耦合到数字计算机总线的音频接口并行地控制数字计算机总线控制器和能够播放音频CD的音频设备，音频设备和计算机音频放大器来播放音频CD而不向中央处理器。

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, memory, at least one drive comprising compressed audio data, and an audio controller coupled to the system CPU, memory and drive. The audio controller is adapted to cause the drive to read the compressed audio data from the drive, to cause the system CPU to decompress the compressed audio data from the drive into decompressed audio data, to cause the decompressed audio to be stored in the memory, and to cause the decompressed audio data to be retrieved from the memory for playing.
摘要翻译：用于计算设备的低功率数字音频解码和播放系统和方法提供了低成本，低功耗，长电池寿命的音频播放和解码系统，其可以用于播放各种格式的压缩音频文件。一方面，适于播放音频文件的计算机系统包括系统CPU，存储器，包括压缩音频数据的至少一个驱动器和耦合到系统CPU，存储器和驱动器的音频控制器。音频控制器适于使驱动器从驱动器读取压缩的音频数据，使得系统CPU将压缩的音频数据从驱动器解压缩为解压缩的音频数据，以使解压缩的音频存储在存储器中，并且使得解压缩的音频数据从存储器中检索以进行播放。
