  • Patent number: 10761867
    Abstract: Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs. Other embodiments concern accelerating dynamic linking by determining certain function calls that, rather than being processed through emulation of PLT code, are instead directly called without the need for PLT code translation. Some embodiments address both nested emulation and accelerated dynamic linking but other embodiments include one of nested emulation and accelerated dynamic linking. Other embodiments are described herein.
