4. Component Interfaces
The component invocation interface is common to all HLS components and contains the return data (for non-void functions) and handshake signals for invoking the component, and for receiving results back when the component finishes executing.
Use the parameter interface to transfer data in and out of your component function. The parameter interface for your component is based on the parameters that you define in your component function signature and global variables (including global streams) that your component accesses.
