Hi,
I have less experience with ecos but I (or maybe a
member of my group) will port eCos for the blackfin
dsp from Analog Devices.
Could you tell me how much time we will need (with
good basic knowledge in computer science) to port
it basicly?
With "good basic knowlege" I'd like to say that I know
whats a pipeline or memory mapped register, memory map
and so on. I also have experience in progamming assembler
and c at machine-level.
Maybe it's easier to estimate the number of codelines to
write.
It's hard to give a time estimate for such work because this
really depends so much on the experience and calibre of the
people doing the work. That said, porting eCos to a new
machine architecture is non-trivial and can take someone with
experience with eCos anywhere from 4-12 weeks (I've done a
number of these and those are representative costs).
Note: I'm not trying to make this sound like a huge task,
rather that there are lots of details to consider and get
correct and it simply takes time, often more than one might
wish.
