IMPORTANT: The Multichannel support from AXI DMA will be discontinued. For MultiChannel support, see the AXI Multichannel Direct Memory Access (PG288) [Ref 12] .
Multichannel mode enables DMA to connect to multiple masters and slaves on the streaming side. A new set of signals associated with source and destination signaling are added. They are:
• tid – 5-bit signal. User-defined sideband signaling.
• tdest – 5-bit signal. Provides coarse routing information for the data stream.
• tuser – 4-bit signal. User defined sideband signaling.
