My understanding is that the processors the micro-controler
class, the ones with memory in the order of bytes or
kilobytes, usually C compilers that only implement part of the
ANSI standard, given the hardware constraints.
Meaning just a very small subset of data types is supported,
limited library support and lots of compiler extensions to
make use of the processor and on die ports.
Nothing like this here - you have all types, you have complete
libm, libc and stdlibc++ with everything you need. There are no
compiler extensions other than a typical GCC __attribute__ used
to declare interrupts, which is not really necessary on most
Cortex-M3 chips. These are really powerful chips with
1.25DMIPS/MHz and clocks around 70MHz (ranging from 24MHz to
204MHz)... There's even a dual-core chip - LPC43xx which has
Cortex-M4F (with single precision hardware FPU and some SIMD
instructions) and a Cortex-M0, both running at 204MHz <:
So these are not very much like 8-bit microcontrollers (AVR,
PIC, ...)
That's why I think D would fit such chips quite nice (; Sans
the GC of course... Maybe without exceptions too, but I don't
think that would be possible (it's pretty hard in C++)...
4\/3!!
Thanks for the valuable explanation.
