Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for executing native code modules. One of the methods includes for executing a native code module includes obtaining the native code module, wherein instructions in the native code module are encoded by variable-length encoding; loading the native code module into a secure runtime environment for an ARM instruction set architecture; and safely executing the native code module in the secure runtime environment using software fault isolation (SFI) mechanisms.
