It does multiple cycles, driving the appropriate byte enables.
When going from a wide to narrow it will do cycles with no byte enables asserted! - Altera_Forum

and could you please comment on this setup for transfering 192b wide stream to SDRAM. channelwidth is 0 and packets are enabled.
Dual clock fifo with 8 bitpersym, 24 symperbeat. => timing adapter latency: 1 to latency: 0 added by sopcb => data format adapter. 8 bitpersym. 24 symperbeat to 4 symperbeat. => sgdma, datawidth 32. => SDRAM datawidth 32. would this be efficient and sensible? i set sgdma datawidth to 32, and enabled packets to ged rid of som errors in sopcbuilder. - Altera_Forum
