My 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?

There'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.

For the cost/benefit ratio? I think you're absolutely right.

But I think it'd be a neat project to learn anyway :)
