TLB Options of virtualization

TLB Tagging options for Virtual machine environment:

1. Process ID tagged TLB --> Tag TLB with process ID. Don't flush during context switch. Little change to OS
2. Object based tagging --> share TLB enteries between objects. Need more changes in OS
3. Snoopy TLB -> Completely transparent to software ( very important). It could be expensive in hardware with added complexity
4. Folded Address Space --> ???

A new beginning...

Ok. I have been lazy in updating my blog - started sometime in 2005. Now, is right time start updating the blog. Finally, I am happy to get my research paper accepted for ACM SIGOPS/SIGPLAN's Virtual Execution Environment (VEE 2007) conference. You can visit conference web site:

Looking forward to go for Internship again this summer and produce more useful results. Soon will post a link to the paper.
