[Discuss-gnuradio] scheduler and special interleaver block

[Thomas Schmid]

Hi Everyone,

I have a question about the gnuradio scheduler and the interleaver block.

Let's assume that we have an interleaver block with two inputs and one
output. Now, is it correct that the gnuradio scheduler runs the
interleaver block only if there is data on both interleaver-input
channels? If this is the case, then it would be complicated if you had
two message sources because the two message sources would be
independent and not generate messages at the same time and of the same
size. Thus, the interleaver block would not work.

Would it be possible to write a special interleaver block which checks
both inputs. If there is input on one channel, but not on the other,
the interleaver interleaves the data from that channel with 0's (or
some other defined value).

Thank you very much for any comments on this issue,

Thomas
