[Discuss-gnuradio] Stream tags and None 1 to 1 processing blocks. Failure to propagate

2011-07-18 Thread Colby Boyer
Hi All, I have seem to run into an issue with the stream tags and interp/decimation processing blocks. When computing to add the tag to the proper output offset, it always rounds down. In certain cases, computed offset is X.YZ, where the first input item to the next block is at X+1. So the stream

Assuming you're using the thread-per-block scheduler, then you just need to make sure any data dependencies are met so-as to not hang the scheduler -- which I think would be pretty hard to do. See also "gnuradio-core/src/lib/general/gr_throttle.cc". - MLD On Jul 18, 2011, at 3:15 PM, Colby Boy

[Discuss-gnuradio] Effect of sleeping a processing block in the middle of the "work" method.

2011-07-18 Thread Colby Boyer
Say, I need a block to wait for some processing to finish down stream before moving on to the next processing stage. Is it OK for me to stall in the middle of the work function via a mutex? Or will this mess up the thread scheduler. Thanks, Colby ___ Dis

Hi all, Thank you for your help. After deeper investigation, software emulated FP is performed form the GNU libsdtc++ because it is compiled with software FP and does some arithmetics on complex (add, multiply) which are struct of floats. I will recompile libstdc++ with hard FP and measure again
