 Here are <a href="http://www.cs.wisc.edu/~austin/talk.scc"> slides</a> from a talk I (<a href="http://www.cs.wisc.edu/~austin/austin.html">Todd Austin</a>) gave at PLDI '94 in Orlando, Florida.  The talk detailed the first incarnation of SCC.  The implementation details are a bit dated, but the description of the basic technology is still relevant.  <p>
