Sir,

I have studied about SASOS. It's really a great approach to make the
process faster by avoiding multiple copies of the data. I read about two
SASOS namely Angel system(developed at City University, London) and Mungi
system(developed by University of New South Wales, Australia). I also
studied about Memory Protection in SASOS, where the concept of address
protection is replaced by protection domain. I studied about
Multithreading, POSIX, Race condition and Synchronization to avoid the Race
condition.
Please guide me, am I  on the right path and what all do I need to learn
further?

Thanks and Regards
Abhinav Jain
