The underpinning problem with Dalvik is that its implementation follows many JVM specifications. For example:
The binary format, not the actual instructions themselves, follows very closely to Java's binary class format (I think this one is a weak argument, but it is one that Oracle is throwing.)
The method used to pre-process the binary code and package the binary so that it can be pre-processed is very similar in both. (This one is a little bit less weak because the binary headers look almost the same bet

AMD has had their own distinct designs since then, and I'm sure that there's just about nothing from pre-386 chip internals that is in any way relevant to current CPU designs.
