what are the differences between PL330 and DMA-330?

PL330 and DMA-330 are the same thing. PL330 is the part number for delivery, and historically we referred to system products by the PL codes. However it was challenging to remember what all the different PL codes were so we moved to naming products with a three letter + three number code, e.g. PL330 => DMA-330,  PL301 => NIC-301 network interconnect, PL340 => DMC-340 dynamic memory controller etc.

Here's a link to the TRM for more technical detail: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0424d/index.html
