The biggest problem with using Ada for this purpose is that most people
(at least those who are vocal) seems to want a complete language
environment for any device.
This does not make sense for a microcontroller market. Microcontoller
seems to work best in polling mode with some interrupt work. In other
words; not the standard Ada way of doing things. The Ada language sans
floating point and tasking is still a powerful and useful language.
Tasking is probably cost effective for some purposes when one uses CPUs
like the 6502, Z80, HD180, 68xx, etc. Floating point with those CPUs are
questionable, but doable. There is a number of floating point libraries
available. Or at least was available when I dabbled in 8 bit assembly
programming on 6502 and Z80s.
For 8 bit work it would be possible to be able to define a generic 8 bit
instruction set (procedures) which can be translated to something
practical for an individual CPU. I'm not sure that efficienciy is
needed,
Greetings and congratulations to ACT,
