Hi,
For a real time embedded system, is there any requirement on the
processor architecture to meet the real time
requirement?
What is "the real time requirement"? I did not know that there was
only one. Every real time system I have worked on so far, and there
have been a lot of them, have had their own different requirements.
Now that we've straightened that out, yes, just about every real time
system usually impose some minimum performance requirements on the
processor/controller/DSP.
The requirements of some real time systems can be met by an original
8051 running at 12 MHz. The requirements require much more powerful
processors.
Does realtime system depend on realtime OS to meet the
realtime requirement?
Some do, some don't.
