[PD] LibPd on microcontroller

I recently send a mail in this list describing my experience of audio synthesis on microcontroler, but i did not use libpd.
i did not recommend libpd for microcontrolers.
in fact, I did not recommend audio processing on hardware that did not have support for float arithmetic.
(only me or crazy nerd do that).
a micro controller to use is for example the cortex M4. You can find them on the teensy hardware.
teensy also provide a audio synthesis library, and is supported by arduino IDE.
You can also have a look at the heavy compiler if you want to embedded a pd patch.

However, I have only encountered LibPd in the context of other applications (processing, openFrameworks) and mobile devices so far. Do you think it could work on an ESP8266? I'm also a bit concerned about efficiency, as computation power is rather limited:
