AC97 Audio Controller
The Beyond AC97 Audio Controller IP Core enables audio control for SoC and FPGA.
Overview
The Beyond AC97 Audio Controller IP Core enables audio control for SoC and FPGA. The Beyond AC97 core offloads audio data handling from the processor by using a dedicated DMA engine. The Beyond AC97 Audio Controller supports AC97 revision 2.3 compliant audio CODECs. External interface supports one external AC97 CODEC with 6 output (3 of them can be Double Rate Audio) and 3 input channels. The product is silicon proven in production silicon.
Key features
- Fixed 48kHz audio support
- Hardware variable sample rate support from 8kHz to 48kHz (up to 96kHz with Double Rate Audio enabled)
- Double Rate Audio support for Left, Right and Center channels
- 16 bit sample size support (18 and 20 bit support planned in future)
- Mono, stereo or multichannel (1, 2, 4 or 6 channels) audio output support
- Stereo Input and dedicated Mono microphone Input Channel support (all together 3 input channels)
- Power management support (individual subsections or full power-down mode)
- Full access to codec registers (tone, loudness, 3D stereo enhancement, etc.)
