Top-Level Dataflow

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
