Data Buffer Update

[Steve_Brooks]

Keeping a rolling buffer of data and would like to make the updating with new data faster.  This will be running in real-time on a cRIO.  I have an array of DVR references per channel because when I put the 2D array of data into a single DVR, when I update each channel, it has to act sequentially which makes it significantly slower.  So the code below is what is called in parallel for each channel.  I have tried many styles, but this is the fastest method I have found so far.  Looking to see if anyone has a faster method I haven't seen before.

Thanks in advance,

I haven't fully benchmarked the differences but I use size limited queues and lossy enqueue when I want circular buffers these days. You do have to fill the queue once to get all the memory allocated but this can all be done up front of starting to buffer real data.

I do the same with size limited queues. Biggest issue is random access to your data, it won't work for that.
