ActionScript VM contributed to Mozilla Foundation

Good news for Mozilla products, soon we could gain as much as 10x performance boost on our JavaScripts / ECMAScripts.

SAN FRANCISCO — November 7, 2006 — Adobe Systems Incorporated (Nasdaq:ADBE) and the Mozilla Foundation, a public-benefit organization dedicated to promoting choice and innovation on the Internet, today announced that Adobe has contributed source code for the ActionScript™ Virtual Machine, the powerful standards-based scripting language engine in Adobe® Flash® Player, to the Mozilla Foundation. Mozilla will host a new open source project, called Tamarin, to accelerate the development of this standards-based approach for creating rich and engaging Web applications.

The Tamarin project will implement the final version of the ECMAScript Edition 4 standard language, which Mozilla will use within the next generation of SpiderMonkey, the core JavaScript engine embedded in Firefox®, Mozilla’s free Web browser. As of today, developers working on SpiderMonkey will have access to the Tamarin code in the Mozilla CVS repository via the project page located at www.mozilla.org/projects/tamarin/. Contributions to the code will be managed by a governing body of developers from both Adobe and Mozilla.

“Adobe’s work on the new virtual machine is the largest contribution to the Mozilla Foundation since its inception,” said Brendan Eich, chief technology officer, Mozilla Corporation, and creator of JavaScript. “Now web developers have a high-performance, open source virtual machine for building and deploying interactive applications across both Adobe Flash Player and the Firefox web browser. We’re excited about joining the Adobe and Mozilla communities to advance ECMAScript.”

The Tamarin project is just getting started so the roadmap is not yet fully developed, but some of the technical goals include:

  1. Integrating the Tamarin VM and garbage collector within SpiderMonkey
  2. Using the SpiderMonkey compiler to generate code for Tamarin
  3. Porting the just-in-time compiler to new hardware platforms
  4. Completing the self-hosting ECMAScript 4 compiler
