about the size of different OS

Hi,

You words make sense really. However ,this is because my research is related to distributed system(not SMP,should be different processors executing separately).

In order to create such an envionment,it would be better if I can put several processors on one signal board because this will save my overall required number of NEEk boards.Boards communication with each other through ethernet.

So now I just do not know which OS should I use (uclinux ,linux or microC) and whether I can create such an envionment(different processors on the same board need to run in different copies of OS,right?)

Does anyone have any suggestion? Thanks:D
