Forth comes in lots of different flavors: The tiniest one I ever used (for a
6502-based industrial air pollution monitoring device) was cross-compiled on a
minicomputer to generate 8-bit tokens for the program ROM. So each “call” of a
Forth function just took a single byte!
The ARM/PRU combination is a perfect fit for a cross-compiled Forth. All of
the compilation functions (“immediate words” in Forth) run on the ARM but lay
down code in PRU-space. PRU-resident native code or lists of Forth function
calls would just be the PRU application itself, plus the tiny bit of code
needed to implement the Forth interpreter. Should be interesting to see what
John has implemented.

Forth is awesome. Last time I had a paying gig in Forth was about 1985, I
think. It was to control a big lighted display board (and garage heater!). So
it was basically a 160 x 32 monochrome graphics editor with fonts and wipe
effects, done on an Apple II (8-bit 6502 processor, 1 MHz, 32k of RAM). No
other language squeezes into tight spots like that.

Nice job John, although I have to admit I have never heard of Forth( and have
been programming since the early 90's ). Nice to learn something new, and I
will have to give the Language a look-see to see if I like it.
Jason, if you're paying attention I would also like a copy of the C compiler.
I am based in the US, and do have an account on TI.com.

I also am interested in C compiler for PRU.
Can you let me know how to contact Jason Kridner?
