==Operating System Compatibility Layer - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17876174 titled 'Operating System Compatibility Layer

==Simplified Explanation==

The technology described in this patent application allows for efficient and secure execution of software compiled for one operating system to run on another operating system. Here is a simplified explanation of the abstract:

* The technology creates a virtualized environment where software compiled for a guest operating system can run on a host operating system.
* The virtualized environment includes a kernel space and a user space.
* The kernel space contains a handle table and the kernel of the host operating system.
* The user space is divided into a restricted space and an unrestricted space.
* The restricted space operates in a restricted mode, while the unrestricted space operates in an unrestricted mode.
* A hyperprocess is implemented, and a hyperprocess handle table is created in the unrestricted space.
* A set of child processes, associated with the guest operating system, is loaded into separate memory address spaces in the restricted space.
* The hyperprocess handle table is shared among the child processes and includes file descriptor tables for each specific child process.

Potential applications of this technology:

* Running software compiled for one operating system on a different operating system.
* Virtualization and emulation of operating systems.
* Cross-platform software development and testing.

Problems solved by this technology:

* Incompatibility issues between different operating systems.
* Efficient execution of software compiled for a specific operating system on a different operating system.
* Secure isolation of guest operating system processes from the host operating system.

Benefits of this technology:

* Increased flexibility in running software on different operating systems.
* Improved efficiency by utilizing the resources of the host operating system.
* Enhanced security through isolation of processes and controlled access to resources.


==Original Abstract Submitted==

The technology provides efficient and secure virtualized execution of software compiled for a first (guest) operating system to run on a second (host) operating system. This includes delineating a kernel space and a separate user space, the kernel space including a handle table and kernel of a host operating system. In the user space, a restricted space is separate from an unrestricted space. The restricted space corresponds to a restricted mode and the unrestricted space corresponding to an unrestricted mode. A hyperprocess is implemented and a hyperprocess handle table is created in the unrestricted space. A set of child processes is loaded into separate memory address spaces in the restricted space, wherein the set of child processes is associated with a guest operating system. The hyperprocess handle table is shared among the child processes and includes a file descriptor tables each associated with a specific child process.
