Hi - I am trying to create optional paths in my Gnuradio Flowgraph. I have found 2 ways of doing this in C++: - Doing a lock() / unlock() inside my heir_block2 and either connecting the items inside the block to the source of the block or connecting the source of the block to a null_sink. - Putting a gr::blocks::copy inside my heir_block2 and either enabling or disabling when I want samples to go through the block.
With the null_sink I get almost no CPU load when the source is connect to the Null Sink. However with the Copy block I get a decent amount of CPU load when the block is set to disable. I looked at the code and looks like a Copy Block set to disable is about the same as a Null Sink. they both just do nothing with the incoming samples. Why is the Copy Block using so much more CPU? Is it possible for it to have the same CPU load as a null sink? Is there are better way of doing this? Should I write a custom block? Thanks, Luke _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
