Abstract: A media processing system and device 100 with improved power usage characteristics, improved audio functionality and improved media security is provided. Embodiments of the media processing system 100 include an audio processing subsystem 301 that operates independently of the host processor 304 for long periods of time, allowing the host processor 304 to enter a low power state. Other aspects of the media processing system 100 provide for enhanced audio effects such as mixing stored audio samples into real-time telephone audio. Still other aspects of the media processing system 100 provide for improved media security due to the isolation of decrypted audio data from the host processor 304.

Abstract translation: 提供了具有改进的功率使用特性，改进的音频功能和改进的媒体安全性的媒体处理系统和设备100。 媒体处理系统100的实施例包括音频处理子系统301，其独立于主处理器304长时间运行，允许主机处理器304进入低功率状态。 媒体处理系统100的其他方面提供增强的音频效果，例如将存储的音频样本混合成实时电话音频。 媒体处理系统100的其他方面由于从主机处理器304隔离解密的音频数据来提供改善的媒体安全性。
