The Vitis™ core development kit also supports streaming data transfer between two kernels. Consider the situation where one kernel is performing some part of the computation, and the second kernel completes the operation after receiving the output data from the first kernel. With kernel-to-kernel streaming support, data can move directly from one kernel to another without having to transmit back through the global memory. This results in a significant performance improvement.
