CrossBridge uses high-performance memory-access opcodes in the Flash Player (known as "Domain Memory") to work with in-memory data quickly.

In 2012, in an attempt to monetize Flash Player, Adobe restricted use of the Stage3D and Domain Memory features of Flash Player under the "Premium Features" brand.

Adobe also developed the CrossBridge toolkit which cross-compiles C/C++ code to run within the Flash Player, using LLVM and GCC as compiler backends, and high-performance memory-access opcodes in the Flash Player (termed "Domain Memory") to work with in-memory data quickly.
