The RPI includes purpose built hardware for DSP in the VideoCore so, probably not.
Poe's law in action I suppose.
I'm all for big data but this is a case of nuking a fly.
- inetknght 8y agoMy understanding was that everything on the Pi except for the video processor was open source. Am I mistaken? Or, are you talking of something different? Or, do you know of an open source library or demonstration of use of the VideoCore for DSP?
- Rebelgecko 8y agoThere's docs and source for some aspects of the VideoCore. I think someone put together an OpenCL implementation, but I don't know how well it works Edit: That said, I think any sort of OpenCL/GPGPU solution is overkill for this problem. I run Flightaware's dump1090 fork on my Pi and it seems to only use around 30% of one CPU core.
