Two UTC instances are used inside the VPAC subsystem. UTC0 deals with real time (RT) transfer , and UTC1 is used for non-realtime (NRT) transfer. Both UTC0 and UTC1 data transfer channels are used for DMA transfers in and out of the VPAC SL2 memory. All 32 channels of the UTC0 are mapped on channel_number = [95:64] and are recommended to be used for real time data transfer only. All 64 channels of UTC1 are mapped on channel_number = [63:0] and are recommended to be used for all other DMA transfer needs of the VPAC subsystem.
All data movement transactions at VPAC subsystem boundary are multiples of aligned 128-byte transfers.
