AVM+ is the ActionScript Virtual Machine
AVM+ offers an order of magnitude performance increase over the “Classic AVM” in Flash Player 7. Our performance target is 10X.
AVM+ implements ActionScript 3.0, the new version of the ActionScript language that is compliant with the ECMAScript Edition 4 standard.
AVM+ is also built for modularity. It will be part of the Flash Player, but is a self-contained module which can be incorporated into other programs with ease. It may also be submitted to the ECMA standards organization as a reference implementation of ECMAScript Edition 4.
Adobe’s reputation for solid engineering shines through here—it seems that what is now Tamarin was designed for integration with other applications from the very start.
