Correct, although to date it has only really been ported to 32-bit
CPUs. There is no fundamental reason why eCos could not be ported to
64-bit platforms, but obviously there may well be problems lurking
here and there. To date nobody has contributed patches related to
64-bit support or paid for Red Hat to do the relevant work.

Similarly it should be possible to run eCos on at least some 16-bit
CPUs, although that term is rather more ambiguous than 32-bit or
64-bit.

That is likely to be a problem. Some of the compiler/linker
functionality that eCos uses, e.g. constructor priority ordering, are
relatively easy when using ELF image format but not with older
formats.
