There is an excellent document entitled The Technology Behind Crusoe(tm) Processors describing the Crusoe's unique software/hardware hybrid available at http://www.crusoe.com/cr usoe/download/pdf/crusoetechwp.pdf. It details how a simple, custom VLIW-like core is combined with a software "code morphing" layer to produce an out-of-order execution unit which is far more sophisticated than than current hardware designs (like the P6 architecture).
