==NATIVE EMULATION COMPATIBLE APPLICATION BINARY INTERFACE FOR SUPPORTING EMULATION OF FOREIGN CODE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18333709 titled 'NATIVE EMULATION COMPATIBLE APPLICATION BINARY INTERFACE FOR SUPPORTING EMULATION OF FOREIGN CODE

==Simplified Explanation==

The abstract describes a method for processing calls between different application binary interfaces (ABI) using a common reference address. The method involves determining whether the reference address is within a memory range storing native code or not, and whether the callee is native or foreign. Based on this determination, the execution of the callee is initiated using different approaches.

* The method uses a lookup structure to determine the nature of the reference address and the callee.
* When the caller is native and the callee is foreign, the callee is called using the reference address within an emulator.
* When the caller is foreign and the callee is native, an entry thunk is called.
* When the caller is native and the callee is foreign, an exit thunk is called.
* When both the caller and callee are native, the callee is directly called using the reference address.

Potential applications of this technology:

* Cross-platform software development, allowing seamless integration between native and foreign code.
* Emulation of foreign code within a native environment.
* Facilitating communication and interoperability between different application binary interfaces.

Problems solved by this technology:

* Incompatibility issues between different application binary interfaces.
* Efficient execution of foreign code within a native environment.
* Simplifying the process of integrating native and foreign code.

Benefits of this technology:

* Improved compatibility between different application binary interfaces.
* Enhanced performance by directly calling native code.
* Simplified development process for cross-platform software.


==Original Abstract Submitted==

Using a common reference address when processing calls between a native application binary interface (ABI) and a foreign ABI. Based on a caller calling using a reference address, a lookup structure is used to determine whether the reference address is within a memory range storing native code and that the callee is native, or a memory range not storing native code and that the callee is foreign. Execution of a callee is initiated based on one of (i) calling the callee using the reference address within an emulator when the caller is native and the callee is foreign; (ii) calling an entry thunk when the caller is foreign and the callee is native; (iii) calling an exit thunk when the caller is native and the callee is foreign; or (iv) directly calling the callee using the reference address when the caller is native and the callee is native.
