Google I/O 2008 - Dalvik Virtual Machine Internals

Dalvik VM Internals
Dan Bornstein (Google)

Dalvik — the virtual machine with the unusual name — runs your code on Android. Join us to learn about the motivation for its design and get some details about how it works. You'll also walk away with a few tips for how to write code that works well with the platform. Be prepared for a deep dive into technical details. Questions encouraged!

I haven't noticed Dan's imperfect presentational skills getting in the way of him presenting something not many people know (or care) about.

FYI, Dan is the designer of the Dalvik VM which makes him the greatest authority on the subject.

half of the question were kind of silly. too bad they wasted all of our time...

[PlanetUbla]

Always a pleasure to listen to genuine geniuses... professional bullshitters, especially politicians, make me sick...

Fantastic vid.

We are working on an upgrade to JNI, which hides the C code from the Java programmer. Have a look at "Returning Control to the Programmer: SIMD Intrinsics for Virtual Machines" for the (ACM) Queue Magazine. It makes sense for google to integrate our approach into future releases of Android, so that Java programmers do not need no write C code. Dalvik VM already does some of this, but not the SIMD stuff, which is really an API add-on on top of Java.
