No, you would just use a DSP with a documented instruction set like the
SHARC. This is used in a lot of pro audio gear. You use LADSPA for
host signal processing and native DSP code for hardware processing.
This is how Pro Tools plugins work - there is one type that runs on the
hardware and another type that runs on the host. I don't remember the
exact terminology.
All the examples from this guide use SHARC DSPs:

Do we currently have any supported hardware with an "open" DSP? The EMU
chips have them but this support was reverse engineered.
