Hello, how can dataflow parallelism be implemented in Intel HLS in the STD edition without using the task mechanism (only available in the PRO edition)? A typical use case is shown here: https://youtu.be/aH1O4DZnjf8 Thanks, Thomas

Hi,

I had found out that the ihc::stream can only used in the Quartus Prime Pro edition based on the link below:

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/hls/ug-hls-getting-started.pdf

I would like to suggest to used parallelize loops in Quartus Prime Standard Intel HLS to increase the parallel dataflow.

You can refer to user guide as link below with the subtitle "Parallelize Loops" which is placed at chapter 4.2:

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/hls/ug-hls-best-practices.pdf

These methods can used reduce the latency as well.

Thanks.

    Thank you for your reply. I think that you're proposing the solution to a different problem, unfortunately not the one addressed in the video. Could you please show how you would implement dataflow parallelism following your approach for the example from the video?
