Hi,
im planning to build an outboard dsp engine. the idea is to connect a fpga device via ethernet to an extra ethernetcard in a linux rt pc system with an alsa driver using rtnet. and the dsp core shall be realized as a pd audio engine/objects.
has anyone a clou how to get started with the portation of that engine, or if its even possible?
bye Ck
A while back someone made Pd run natively on a DSP chip, I think it
was called the Gluiph. That might give you some useful info on this
project:

It depends on whether you want to make a FPGA that can run any Pd DSP patch, or whether you want to turn Pd DSP patches into a different FPGA each.
In the latter case, the most similar projects that I heard about are #77 and #78 in http://www.resmiq.org/projets.php , but the text is probably not online. But then I think that Pd DSP patches can be compiled to FPGA much more easily than Scheme can (which is what those guys attempted) in their case, even though they only attempted to port a purely-functional subset of it.
