My specialty is hardware, logic and machine programming. I know that down the road, I will be looking into trying to run pd on my own boards. The thing is, I don't really know anything about the language pd is written in, or more importantly, the nature of a pd patch's disassembled code.

Does anyone know if pd code can be easily run on architectures other than x86 and ppc?

I have alot of experience on the moto 68000 series, which at 16MHz is probably fast enough for some wavetable syntheses and alot of control comptations, right? That's where I would like to start.

I'm also interested in some other cpu's that I haven't delved much into yet.. the hitachi SH-4 looks attractive for embedding in a pd board, with its built-in logic for fourier transforms and matrix math (which I think would be nice for an audio-responsive GEM patch).

"68000 series, which at 16MHz is probably fast enough for some wavetable syntheses and alot of control comptations, right? "

Yay!! 68000 - are those things stil around? 68010 was what I used for my final year comp sci project back in '90, iirc you can get 16 channels of 16 bit 44k audio with ease, going right through the CPU without a DMA controller to a PCM54 DAC. I had all my wavetables stored on EPROM.

In theory PD will run on anything you can compile it for. Probably best to start with only, main, arithmetic, file, dac etc and leave out the gui and fancy stuff until you get some results. Maybe ask on the list about a "minimal Pd". For fixed point processors there is Pda.

Sounds like an interesting direction you're taking with embedding Pd. Perhaps, for very modest CPUs/microcontrollers a "control only" version of Pd that only does message domain stuff would be interesting.

You should have a look at puredata anywhere (puredata port to linux for handhelds).
