What do you mean by separated pipes here? I was currently planning to use 2
pipes, one for each direction, this is compatible with FPGALink, UART, SPI,
... . Separate bidirectional pipes for configuration/command/status and for
data storage would probably be useful, were you describing something like
this? Since you are talking about a common implementation in host software
you probably meant something else.
