DACU access
[Pipeline details]

A few details
The Data Address Calculation Unit (DACU) handles the Unified Memory, by mapping Unified Memory addresses into Register File, IO File or Data Memory addresses.
It also transparently places access requests to RF, IOF or DM, as response to UM access requests.
More details on DACU requests can be found here.
