1. At least one non-transitory computer-readable storage medium comprising instructions configured to enable a target device with a target instruction set architecture, in response to execution of the instructions, to provide an instruction set architecture bridging layer to the target device to facilitate a library service of a library of the target device to callback a callback function of an application operating on the target device; wherein the library service is implemented for the target instruction set architecture, and the application is implemented at least partially for a source instruction set architecture; and wherein the instruction set architecture bridging layer includes a source instruction set architecture emulator and a library emulator configured to cooperate to enable the application to call the library service, and the library service to callback the callback function, across the source and target instruction set architectures.
