Note: Users interested in providing feedback on the Intel High Definition Audio specification or planning
The Intel High Definition Audio controller utilizes multi-purpose DMA engines, as opposed to
dedicated DMA engines in AC ’97, to effectively manage the link bandwidth and support
simultaneous independent streams on the link. The capability enables new exciting usage models
with Intel High Definition Audio (e.g., listening to music while playing multi-player game on the
internet.) The Intel High Definition Audio controller also supports isochronous data transfers
allowing glitch-free audio to the system.
to implement the Intel High Definition Audio specification into a future product will need to
execute the Intel High Definition Audio Specification Developer’s Agreement. For more
information, contact [e-mail].
AC ’97 2.3 Controller
The ICH6 integrates an Audio Codec '97 Component Specification, Version 2.3 controller that can
be used to attach an audio codec (AC), a modem codec (MC), an audio/modem codec (AMC) or a
combination of ACs and a single MC. The ICH6 supports up to six channels of PCM audio output
(full AC3 decode). For a complete surround-sound experience, six-channel audio consists of: front
left, front right, back left, back right, center, and subwoofer. ICH6 has expanded support for up to
three audio codecs on the AC-link.
In addition, an AC '97 soft modem can be implemented with the use of a modem codec. Several
system options exist when implementing AC '97. The ICH6-integrated AC '97 controller allows up
to three external codecs to be connected to the ICH6. The system designer can provide AC '97
modem with a modem codec, or both audio and modem with up to two audio codecs with a modem
codec.
