| 10 | The Audio Hub (AHUB) comprises a collection of hardware accelerators |
| 11 | for audio pre-processing, post-processing and a programmable full |
| 12 | crossbar for routing audio data across these accelerators. It has |
| 13 | external interfaces such as I2S, DMIC, DSPK. It interfaces with ADMA |
| 14 | engine through ADMAIF. |

| 63 | Contains list of ACIF (Audio CIF) port nodes for AHUB (Audio Hub). |
| 64 | These are connected to ACIF interfaces of AHUB clients. Thus the |

| 66 | have depending on the SoC revision. |
