@azonenberg@ioc.exchangeAnd another nice shader speedup. Not quite the massive boost of the vector frequency/phase filters, but it's next in line after them.
I'm gonna use this random-access LFSR trick on so many filters that work with scrambled data lol.
v0.1.1 (20M point memory depth)
* PRBS31 generation: 65 ms
* PRBS31 verification: 360 ms
Latest (20M point depth)
* PRBS31 generation: 3 ms (21.6x)
* PRBS31 verification: 1.7 ms (211x)
@azonenberg@ioc.exchangeCurrent summary of all of the GPU acceleration work I've been doing in ngscopeclient since v0.1.1.
Other than the CDR PLL and eye pattern which were high-priority targets that were worth the effort, and the Ethernet which I got nerdsniped on, these are all trivial inner loops of just a few lines that I threw at the GPU without any significant tuning, so there's probably more performance upside.
But I'm not complaining with what I've pulled off so far. (As you ca…
