| Interface Name* | Type | Description | 
|---|---|---|
| h2ddm_desc | AVST Sink | H2D data mover gets the descriptor from external descriptor controller. Data mover throttles external descriptor controller with ready signal. | 
| h2ddm_desc_cmpl | AVST Source | H2D data mover sends the completion (descriptor data from host memory) to external descriptor controller on this interface. | 
| h2ddm_desc_status | AVST Source | Once a descriptor is complete, H2D data mover sends the status information (success, error, descriptor ID, application specific bits) to external descriptor controller | 
| h2ddm_master | AVMM Write Master | This interface provides the read data from the host memory to the user application. |
