The two DMA controllers (DMA1 and DMA2) have 16 streams in total, each dedicated to managing memory access requests from many peripherals.

is there a conceptual difference between the terms "Channel" and "Stream"? Do the terms require/determine, for example, the allowed number of concurrent Consumers or Producers?

I'm currently developing a Channel/Stream of DataFlowVariables, which may be written by one producer and read by one consumer as the implementation is destructive/mutable. Would this be a Channel or Stream, is there any difference at all?

Thanks
