2007-10-07 Thread seph 004
I was wondering if someone could perhaps clarify how the gr_message_sink works . I'm trying to make a modified version of the fft_sink. I noticed that the sample stream is turned into a vector streasm and then sent to a message sink. When the data is unpacked from the messages, then it se

Eric, Before even thinking about libpmt, it would be wise to figure out the much greater CPU consumption in libc. Start with the big offenders. When that's sorted out (and we're confident about your profile numbers) we can have a discussion about what's next. Sounds good. BTW, what is the
