There is atypo in the document that can cause some confusion whichis going to becorrected in the next release.
The burst length is1024, but this is in bytes (not words).So, bursting is actually being performed at 256*32-bit words, whilethe documentationindicates 128. The burst size was increased from 128 to 256 to help with real world MPMC performance issues, but the documentation was not properly updated to reflect this change.
Also, Figure 1 below is a screenshot of a full burst simulation followed by the start of the second burst.Theremight be some confusion because the command bus does not align with the start of the data burst.The next command is queued into the VFBC early, that is, before the last data burst ends.
