Mainstream Chrome spits ARM, Intel apps on the fly from cross-platform code
Architecture, smarchitecture ... Get .exe speed on the web
Google has shipped the stable release of version 31 of its Chrome web browser, and with it the first generally available version of its Portable Native Client (PNaCl) compiled-code technology for the web.
Because NaCl modules are essentially binary executables, however, developers must build separate versions of them for each processor architecture, including 32-bit and 64-bit Intel chips, ARM, and so on.
PNaCl (pronounced "pinnacle") eliminates this problem by compiling the modules into an intermediary format instead of executable code, then having the browser complete the final compilation step for whichever architecture it's running on.
The tech is now available in the stable releases of Chrome for Windows, OS X, Linux, and Chrome Frame.
Google wouldn't mind seeing it show up in other browsers, too – it's open source – but don't hold your breath. The Mozilla Foundation, for one, has pooh-poohed the idea of browsers running native code since Google first floated it in 2010. Microsoft, on the other hand, has offered ActiveX as its own take on native code for the web for years now and isn't likely to change gears.
