As i know CFLEA produces compiled psewdo-code and this code is
executed by virtual mashine.
In that Atmel book processor was AT89c2051 (2kB flash), "p-code"
was in serial eeprom, so can be at least 64kB - i think there
can be such configuration in real device . One advantage is
that it will be easy to change software (change EEPROM) or
even one can have "library" with different EEPROMS for different
tasks. This is offcourse only opinion, i was never build something like this - partially because i was never found
simple enough "p-code" system for 8051. On other hands -
i build one device (,which controls plastic mold mashine of my friend) - something like industrial controller. Software is like interpreter (my own concept for PLC ;-) - loops, timers, io, counters,conditional branches, but no math ), stored in internal flash, user programm is stored into serial eeprom.
So i found it can be usefull to have "slot" to change this
eeprom - for example with "safe" version, when diagnostic is
needed.
My device is much near to Basic mashine, and i tink
Basic with seriall eeprom support will be great. Maybe
Basicstamp is something like this, i dont know.
