Hello all, I'm a grad student writing my first GNU Radio processing block, and I'm a little stuck. I'm not sure how to tell GNU Radio the input output relationship of my block. The block takes 2 inputs. One is an index, and the other is data (I may use stream tags to indicate index in the future). The block also has one output port of processed data. The block needs to buffer a small history of inputs then search through for matching indexes. When it finds a matching pair of indexes, it processes the 2 pieces of data corresponding to the two matching indexes (i.e. has the same position in the buffer) and produces 1 output. The trouble is, there is no guarantee it will find a match. The result is that sometimes there is no output, and sometimes there are multiple outputs. I'm not sure how to setup GNU Radio's buffers to accommodate this. I'm getting close to a solution, but I thought I'd ask here. So, if I wanted to buffer say 8 index and 8 data items, and then arbitrarily pluck matching data from the input buffer to process and put on the output buffer, how would you recommend I go about it? Thanks, Nate

Hi Nate, I met the same kind of problem: the ratio between input and output of my block is gonna change depending on the content of the data.Have you solved it? Thanks, Niko.
