Stream Inspector v2
Stream Inspector v2
Hi,
I've converted my "Stream Inspector" Debug tool to FS and on the way I just found a better solution. So now, here is Stream Inspector v2:
It counts the "events" inside a stream eg. if there is "not a number" or "infinite" which can cause serious problems. It can also detect denormals.
The new version, does the detection in pure x86 assembler, so even when there are denormals, they don't have a huge effect on the counter. It is also more accurate, so it basically can't miss one sample.
I've included a DC Lowpass, that tries to find the DC Offset. It does that directly in stream, and it can go down into denormals (it is supposed to be so)... so when there are denormals, there are CPU spikes.
Hope it's usefull.

Re: Stream Inspector v2
Many thank, MyCo, that is such a useful tool to have! 
All schematics/modules I post are free for all to use - but a credit is always polite!
