Hi, I would like to use scratch space within the output buffer of a block, but not sure if I can rely on the scheduler not altering the content of those items in the output buffer that I have written to but have not made it available to downstream blocks within general_work. I know how blocks, forecast, general_work and history works, but I think my use case is not covered.
A simple toy use case would be to implement a fir filter without the history call (I know that in this case history is better). Once a new sample is taken from the input you multiply that with an N-length kernel and add it to the output buffer and output only one item and zero out N-item ahead. Can I rely on the scheduler not to modify unproduced items (but of course within the limits of ninput_items)? Should I return 0 for forecast when there is not enough space in the output buffer? Would such a block be synchronous? Best, Miklos _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
