US Patent 10162617 Binary translation into native client

Systems and methods for binary translation are disclosed. In some implementations, guest software to run in a Native Client environment is received. The guest software is configured to execute at a specified guest hardware architecture and not within the Native Client environment. A binary translation of the guest software into Native Client compatible machine code is provided using emulation software. The Native Client compatible machine code executes within a sandbox for the Native Client environment. The Native Client compatible machine code is executable within an application. Providing the binary translation of the guest software into the Native Client compatible machine code for execution within the sandbox occurs just in time, during a runtime of the emulated guest software, and without porting or recompiling the guest software. Providing the binary translation interleaves with execution of the emulated guest software.
