Intel® High Definition Audio (Intel® HD Audio) Controller Capabilities
The Intel® HD Audio controller is the standard audio host controller widely adopted in the PC platform, with industrial standard Intel® HD Audio driver software available for Microsoft* Windows* and many other Linux* based Operating Systems. Intel® HD Audio controller capabilities are listed as follows:
- Baseline Intel® HD Audio operation with legacy DMA transporting audio stream to / from audio codecs, with host processor carrying out the audio processing
- Low power audio operation with offload DMA transporting audio stream to / from the Audio DSP offload engine offloading the audio processing from host processor
- Ability transport audio stream to various audio codecs speaking different link protocols with the same audio host controller view from SW stacks
- PCI / PCI Express* controller
- Supports data transfers, descriptor fetches, and DMA position writes using VC0
- Independent Bus Master logic for 16 general purpose DMA streams: 7 input and 9 output
- Supports variable length stream slots
- Each audio stream supports up to:
- Supports memory-based command/response transport
- Supports optional Immediate Command/Response mechanism
- Supports output and input stream synchronization
- Supports global time synchronization
- Supports MSI interrupt delivery
- Support for ACPI D3 and D0 Device States
- Supports Function Level Reset (FLR)
- Support Converged Platform Power Management (CPPM)
