3.1.10.3. Host Channel Top Connection to OpenCL Kernel

To stream data to kernel, Avalon® -Streaming stin and stout ports are used. To clock cross into kernel clock, two Avalon-ST dual clock FIFO should be instantiated.

For one FIFO, the in port should be connected to the stout port of the host channel top, while the out port is exported. For the second FIFO, out port should be connected to the stin port of the host channel top, while the in port is exported.

In the board_spec.xml, the host channel ports are IO ports.
