 In cases of high sample rates where the required data rate exceeds the PS-PL
 interface's available throughput, the data is transmitted in a loop from a

+For lower sample rates, the :git-hdl:`data_offload <library/data_offload>`
 can be placed in bypass mode, in which case the DMA must stream the data
 from the PS memory.
