Subject: [Qemu-devel] Time complexity for self-modifying code
Date: Thu, 08 Feb 2007 15:01:57 -0500 [thread overview]
Message-ID: <45CB81B5.9080405@gmu.edu> (raw)
Hello. I'm a student at George Mason University and I had a question
regarding the time complexity of QEMU's algorithm for dealing with
self-modifying code.
From looking at the QEMU Internals documentation
(http://fabrice.bellard.free.fr/qemu/qemu-tech.html), it seems that
QEMU's method for handling self-modifying code might have different
algorithmic efficiency classes for it's average case and worst case. As
in, on average I assume that QEMU emulates instructions at O(n)
efficiency. In the worst-case, might self-modifying code change the
efficiency of QEMU to another order of efficiency, such as O(n^2)? Any
thoughts would be greatly appreciated. Thanks!
