AC97 Audio Controller
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.
