  • Number of translations that can be performed at the same time.
  • Number of translation requests that can be accepted from all DTI masters.

For the TBU, you can configure the following:

  • Write data buffer depth.
  • Size of each cache.
  • Number of transactions that can be translated at the same time.
  • Number of outstanding read and write transactions that the TBM interface supports.
  • Width of data, ID, user, StreamID, and SubstreamID signals on the TBS and TBM interfaces.
