<p>A number of academic publications nicely describe many aspects
of Valgrind's design and implementation. Online copies of all of
them, and others, are available on the <a class="ulink" href="http://www.valgrind.org/docs/pubs.html" target="_top">Valgrind
publications page</a>.</p>
<p>The following paper gives a good overview of Valgrind, and explains
how it differs from other dynamic binary instrumentation frameworks such as
Pin and DynamoRIO.</p>

<p>The following two papers together give a comprehensive description of
how most of Memcheck works. The first paper describes in detail how
Memcheck's undefined value error detection (a.k.a. V bits) works. The
second paper describes in detail how Memcheck's shadow memory is
implemented, and compares it to other alternative approaches.

<p>The following dissertation describes Valgrind in some detail
(many of these details are now out-of-date) as well as Cachegrind,
Annelid and Redux. It also covers some underlying theory about
dynamic binary analysis in general and what all these tools have in
common.</p>
