Description
This message reports a possible throughput improvement.
Explanation
If the user code has dataflow at the top-level function, and if the user wants to execute the kernel in a pipeline mode, then it is not possible with an ap_ctrl_hs protocol. For more information on the protocol, see Defining Interfaces.
Solution
Multiple kernel executions can be overlapped for performance improvements if the user specifies the below interface pragma.
#pragma HLS INTERFACE mode= ap_ctrl_chain bundle=control
