Today I find out very interesting project: Adobe Alchemy – "A research project that allows users to compile C and C++ code into ActionScript libraries (AVM2).". It’s in a preview state. Published on 17 Nov. There are some quotes from Adobe webpage:
Alchemy, Web application developers can now reuse hundreds of millions
of lines of existing open source C and C++ client or server-side code
on the Flash Platform. Alchemy brings the power of high performance C
and C++ libraries to Web applications with minimal degradation on
AVM2. The C/C++ code is compiled to ActionScript 3.0 as a SWF or SWC
that runs on Adobe Flash Player 10 or Adobe AIR 1.5.
is primarily intended to be used with C/C++ libraries that have few
operating system dependencies. Ideally suited for computation-intensive
use cases, such as audio/video transcoding, data manipulation, XML
parsing, cryptographic functions or physics simulation, performance can
be considerably faster than ActionScript 3.0 and anywhere from 2-10x
slower than native C/C++ code. Alchemy is not intended for general
development of SWF applications using C/C++.
Alchemy, it is easy bridge between C/C++ and ActionScript 3.0 to expand
the capabilities of applications on the Flash Platform, while ensuring
that the generated SWCs and SWFs cannot bypass existing Flash Player
