just my opinion: Vxworks has many funcitons which support task spawn, interrupt handle, i/o port read/write. I think that's why it's called real-time.
I don't know about WindowsCE. But windows used to wrap up a lot of things and developer is not easy to get the works done directly.
为什么说 VX works 是real-time embedded system 的系统.而window CE只是embedded system ? What is the "real time" features there in VX works? Someone can explain a bit? Thax
