[ECOS] ECOS - MIPS

I am new to eCos and embedded programming and still have lots to learn  
about both. Probably like yourself I am experienced in *nix and Windows  
programming with boundless resources. My initial impressions were that the  
coding style in eCos was rather old fashioned. We are probably both used  
to the amazing things that can be done with STL, boost, template  
metaprogramming etc. However I realise that many of these libraries and  
techniques are not appropriate for embedded programming. On the other hand  
it is possible that some modern C++ techniques could be useful in this  
context. Currently I do not have enough experience of embedded programming  
to give an opinion.

Could you provide an example of how some part of eCos could be improved  
using a specific design pattern. This could form the basis of a more  
focused discussion of the benefits of what you are proposing. If your  
ideas are practical and would genuinely make eCos more easily configured  
then I am certain that the eCos maintainers would be very happy to help  
you incorporate them.
