[hpsdr] Odyssey dsPIC33 RAM usage

[Frank Brickle]

Oh boy, are you going to be sorry you said this.

Anyway, concerning implementation platforms (like Python+linked code), code
generation, and so on...
if you're interested in this topic, you can see a splendid example of
evolution in full public view:
<http://ccrma.stanford.edu/software/clm>
"Common Lisp Music is a music synthesis and signal processing package in the
Music V family. It runs in a number of lisps or as a part of Snd (using
Scheme or Ruby). The file README.clm has current status info for the Common
Lisp versions."

Of specific interest here is the range of platforms that clm runs on, and
how -- and how it supports pretty much all of the most diverse environments
without ceding too much in enhanced features.

In particular, the author (the most excellent Bill Schottstaedt) provides
one mode where, if you want, an entire clm program is turned into
human-readable C code that can be compiled and run standalone. The same
program can be run as one of the many Lisps using optimized C libraries, or
it can be expressed in C, Scheme, Ruby, or Forth, or run as a subsidiary
process inside Bill's waveform editor, snd.

The key capabilities are (1) a good set of application-specific libraries
and (2) a tree-walker for Lisp expressions that can absorb a clm program
whole and churn out whatever kind of execution policy you like.

Of most importance for the discussion at hand is that the basic processing
algorithms don't need the capabilities of a full Lisp environment. In fact
-- here's the punchline! -- the programs can mostly be expressed in...XML.
You can see where this leads.
