Audio Voice and Speech

The AVS subsystem builds upon the AVS features of previous platforms to provide a richer user experience. This section will cover the HW features used in the processor for use within the AVS subsystem. The AVS subsystem consists of a collection of controller, DSP, memory, and link interfaces that provides the audio experience to the platform. This subsystem provides streaming of audio from the host SW to external audio codecs with the host processor and/or DSP providing the audio enrichment.

The optional DSP can be enabled in the audio subsystem to provide low latency HW/FW acceleration for common audio and voice functions such as audio encode/decode, acoustic echo cancellation, noise cancellation, etc. With such acceleration, the integration of the AVS subsystem into the processor is expected to provide longer music playback times and VOIP call times for the platform.

The key HW features of the AVS Subsystem are described in the following topics:

  • Intel® High Definition Audio (Intel® HD Audio) Controller Capabilities
  • Audio DSP Capabilities
  • Intel® High Definition Audio Interface Capabilities
  • Direct Attached Digital Microphone (PDM) Interface
  • USB Audio Offload Support
  • Intel® Display Audio Interface
  • MIPI* SoundWire* Interface
