Hi guys! I am trying to extend ISA to make CPU can
notify L1$ controller. I have learned how to extend ISA by
following http://pages.cs.wisc.edu/~david/courses/cs752/Fall2015/wiki/index.php?n=Main.Homework2.
But it's still so hard for me to achieve my goal.My imagine is like that CPU
get such instruction ??or some manners to notify cpu?? and then send
packet,which contain special cmd,to L1$ controller.Then the L1$ controller can
vertify "pkt->isNotify()==true" .
Could any body give me some suggestion?
Thanks a lot!
